1) Drawing lines on a shop window with a felt-tip so it looked broken from a distance.

Not really evil but I used to move stuff around at my Grans to make her think she was losing her memory. I'd put bleach in the fridge and orange juice under the sink etc.

Although I wasn't a child when I did this, it still deserves a mention.

I used to live in halls of residence, in a flat with 9 other blokes. One of them was a gadgie from a small town almost as far as you can go into Wales, Haverfordwest. He was incredibly naive. He was 19, and until he moved to Nottingham had never been to a nightclub, never been with a lass, or had a kebab.

Another of the lads was a bloke from Rugby who we were all convinced was a bummer as he shaved his head, listened to Queen and always hung about with lasses (but never got into any of them).

Anyroad, it was the welsh gadgie's 20th birthday, and he got incredibly blaked on a bottle of vodka. Eventually he passed out, and we put him on his bed.

Now I had a bottle of Ambre Solaire after sun milk, which to be quite honest looked like man-milk. So a nasty plan formed. I unravelled a johnnybag and filled it with some of said after sun milk. I got a Kit Kat, melted it with a match and wiped it up and down the outside of the johnnybag so it was streaky brown. I then left the mocked up used sheath on welsh gadgie's bedroom floor as he lay snoring.

The next day he awoke, naturally not remembering a lot about the night before. I told him that we had put him to bed, and as we were concerned about him choking on his sick, the lad from Rugby had volunteered to watch over him.

The rest of the day all the other lads kept asking him if he'd been for a dump, and if he felt OK. Eventually at about tea time he lost his rag and went looking for the lad from Rugby as he was by now convinced he'd been rogered in his sleep. One of the lads intercepted him and told him the truth. Thankfully he saw the funny side of it, and we are still mates now.

not really evil?

god,thats a horrible thing to do to ter nanna
