From September until December of 1998 I lived in a student flat with three other men.
Whilst I could just let you use your imaginations, I will elaborate. The truth may even be more disgusting than what your terrifying brains can conjure. But I'm willing to be proved wrong :-)

Our story revolves around two pints of milk in a plastic container thingy (what are they called anyway? They're not cartons. Cartons are made of cardboard) which quite literally sat in our kitchen, unclaimed, from September to late November. Our kitchen was, as you might expect, fucking disgusting. There were four of us, so it took about a week to get to the point where if you wanted to cook, or eat off a plate instead of out of takeaway wrappings (rare), or drink beer from a glass instead of from the can (Guinness nights only), you HAD to wash up. But none of us ever washed up more than what we needed right there and then. So two pints of milk just blended into the general carnage until it visibly solidified under the plastic.

I never knew milk could turn black.

A bit of background. Being a boys' flat we were not big on originality. We played Tekken 3, a lot, watched films, drank beer and wound each other up. This last point is especially pertinent to the story. When first I moved in I drove up from Nottingham with a carful of stuff, none of which I still own since I came to discover DVD players/a modicum of fashion sense/a more attractive woman than my then-girlfriend. The others had already moved in and informed me in advance that they would be in the pub when I arrived. Steve said he'd leave a key inside the bathroom window, so I just needed to pop round the back and reach through, then let myself in.

Steve failed to mention the full condom he would enclose the key in for "security" purposes.

The bathroom window was one of those frosted affairs so I was reaching in blind. Imagine the horror. I was expecting something hard and metallic; instead my fingers found a prophylactic filled with a suspicious cloudy white liquid. Try to guess how it feels to work out what you're holding as you drag it back through the window.

So I did what I'm confident any one of you would have done; I let myself into the flat, washed my hands incredibly thoroughly, was a bit sick, unpacked the car, marched over to the pub, bought a pint, downed it, bought another pint and walked into the bar where my flatmates were playing pool, loudly referring to Steve as a disgusting cunt. After they'd finished laughing, by which time I needed another pint, Steve assured me that the worrying substance my key had been swimming in was garlic sauce.

"Don't believe me? Smell your fingers"

Nice. My revenge was a long time coming - not because I believed it was a dish best served cold or anything (spaff is usually quite warm in my experience) but because creativity abandoned me in my stereotypically bombed student mindset. Until I asked, for the hundreth time, whose fucking milk was turning black in the fucking kitchen you disgusting fuckers. And then I had an idea.

Many of you will have worked out where I'm going with this. Bear with me, it was fucking funny.

Steve was, and still is to my knowledge, I don't know, I haven't seen him in years, look him up on Facebook if you really want to know, cyber-stalking is so easy these days, seeing a lovely girl called Donna. We all liked her, and I almost feel sorry for how much she had to suffer as part of my hideous prank. I timed it for when they had a weekend away at her parents'. I took a bowl from the kitchen - picked one which had curry smears around the rim for extra "eeewww, fuuuuckk" factor - and decanted as much of the substance formerly known as milk into it. This remains one of the most hideous experiences of my life. The stench of three-month-old milk is ungodly. It rates somewhere between "Rancor" and "Gillian McKeith" on my patented disgustingness scale.

I then placed this bowl under Steve's bed.

Alongside a box of tissues...

...and a borrowed (honest) copy of "Red Hot 60+" magazine.

I then closed the doors and windows of Steve's room and forgot all about it until the Sunday night, when Steve and Donna returned to our flat for a night of "oh thank god we're out from under the parents' watchful gaze let's have lots of sex" sex.

Myself and the other lads were watching TV in the front room until we heard a frankly inhuman noise coming from Steve's room next door. I muted the TV and sit upright in alert, gleeful anticipation. With hindsight, this may have identified me as the culprit. After a series of half-choked exclamations were crescendo'd with a very, very loud "WHAT THE HOLY FUCK?!!", Steve stormed into the next room demanding to know who had sucked the air out of his room and replaced it with camembert in a gaseous state.

I wish I could tell you I said something witty about garlic sauce, or smelling his fingers, but I was laughing so hard that witty repartee was even further from my grasp than normal. Again, not helping any claims I may have laid to innocence. Steve was proper angry. Apparently the stench and the discovery that her boyfriend was rubbing one out over grannies then keeping the produce of said self-flagellation in a bowl under his bed for long enough for it to turn black and solidify like some hideous splunge Star Trek villain (think of the episode where Tasha Yar dies) was a right turn-off for Donna.

I calmed down long enough to assure him that I'd planned for this eventuality and he could keep the mag for as long as was necessary.

And then he hit me.

Totally worth it.

Length... three months, in a warm kitchen, before it was unleashed into a hot room. Think about it. SO proud of myself.
