Your friend must be seriously dumb when it comes to computers.

I once called a friend and his mom picked up, out of nothing I thought it would be funny to start doing voice acting so I started speaking with a different accent and a different pitch and told her that her son was lost at the airport so she had to pick him up.

I got suspended for about 3 days, shit was funny, in the end a few friends requested me to make a "chain" and I blamed around another 14 people because they told me they wanted to be suspended, we ended up making an small party.

I got my uncle's car keys and froze them into ice cubes.

Then after a week I gave him the keys back in his lemonade.

XD

once at school i brang a camera and hid beside the girls toilet...
then they came ut and i snapped a shot and they shouted at me and chased me until i slipped over then they grabbed the camera and chucked it at my balls (have no idea why)

Then i was lying on the ground covering my bits and moaning for like 20 mins.

IT WAS FUNNY!!!

Mike2k5 reminded me off the time my friend was first so I gave him a cup of hot water (not boiling). You should of seen the look on his face.

My friends and i prank called walmart saying we were stuck in the bathrooms. And we called once saying we lost a ring in there and we got a guy to look in there twice!

I tried the "pickle-dick" prank on one of my friends.
DID NOT END PRETTY.

I once prank called someone saying that I lost a baby named Shithead (pronounced Shi-Theed). The funny thing is that the person wrote down the name and didnt even realise it.
funny stuff

That's something you'd do sober.

There was this guy once at a mcdonalds, I got shrink wrap, put it on top of the toilet (not the top seat thingy, just the part where the feasies go) then he went, never noticed and screamed for his life and tried to sue them. His screams were the FUNNIEST yells I've ever heard in my life.

Was up all night wih my Friends yesterday, prank calling some random guys :o We tricked some kid into going to the airport to wait on the love of his life.
