Greatest prank you pulled on another~

[Blaaaaaaaah]

A conversation with Chinh yesterday reminded me of a prank my friends and I did during high school (year 9 or 10), so I thought I should make a thread to post the pranks we've done for a laugh!

The one I remembered was when I was sitting with my friends in the quad at school during lunch, and we were bored. This friend was drinking some ribena, but she didn't feel like drinking the rest, so she started dripping some ribena onto the concrete. She was like "lol, this looks like blood", and this other friend was like "you know what? Let's try putting that on a pad!" So then, someone took a pad, opened it, and we started dripping the ribena onto the pad. Let me tell you now, we were all a bit grossed out by the look of it at first, because it looked really real. We were like "OMGGG IT REALLY LOOKS LIKE A BLOODY PAD!!"

After making the pad look like someone's pad who had been having a heavy day, this friend picked it up and ran to another group of friends that were sitting close by. She threw the pad onto one of them as she screamed (to scare them, of course), she sent the whole of the other group screaming! They all stood up going "OMG AHHHHHHHH" and then ran away! LOLOL! It was so hilarious and entertaining to watch from the side! Hahaha! xD

So what mischief have you done before?
