Cereal Killer
Upon returning from a holiday to japan a friend at work brought back the obligatory bags of dried fish and other unidentifiable nastiness that is inedible by us westerners.

They sat there untouched for months until one day, when extra bored, I hatched a cunning plan to boost moral. This was to insert a handful of the tiny stinky fish things into one of the miniature boxes of cereal another member of the team used to eat in the mornings.

It was masterful, whilst he was in a meeting one afternoon I went in though the bottom of the little carboard box, prised open the inner bag without damaging it and inserted the piscine suprises. Whatever sealed it in the first place was moist enough to reseal without any visual indication of tampering, and then I simply prit sticked the bottom of the box back together. You really couldn't tell that anything had been done to it. Of course by now everyone was in on it and we all waited for the next morning in anticipation of the great merrment.

Cue him going off cereal.

Six months later and in a different office we'd pretty much given up hope of him every eating the box of cereal sitting on his desk. Then one day he stands up and publicly announces "Hmm I really fancy some cereal".

He actually screamed when they came out.

I have never seen an entire office laugh so hard.
