Party pegs
A simple one but it caused me and some friends of mine much mirth.
When I was at uni, there would inevitably be a house party every now and again. Before attending such events, I made sure to stock up on cheap pegs, such as those used to do the laundry. During a party, whenever someone came within range for a long enough period, I would surreptitiously attach a peg to a crease or fold in their clothing. Sometimes if they were there for long enough I'd make it two or three.

The head-messing aspect came not from the victims but from the confused look of other party patrons who would notice various people wandering around with pegs attached to their clothing.

Do I know you?
I used to do the exact same thing. It's amazing how many pegs you can fit around the bottom of a trenchcoat or on a hood…

I doubt that you know me.
This was in Swansea, if that helps.

I have heard of other people doing the same thing; I was introduced to the idea by a friend of mine so he obviously heard it from somewhere else.

Mr Hatter
Loony maths teacher at my old school, not one that taught me, though. Some boys from another class used to add pegs to his coat when he was 'otherwise occupied'.
Seems more common than expected.

I was once invited to a Pegging Party, but somehow that's not what I imagined

pegged my mate's coat once
he got all the way home before noticing and even then, his mum had to tell him it was there.
