What's the funniest prank you've ever pulled on a teacher or friend?

I pulled the fuse out of a firecracker, then lit it and threw the harmless firecracker into the hood of my buddy's sweater. He stopped dropped and rolled in midair, it was awesome

i came from the john and when i passed by the board where my teacher was standing i farted loud.

My friend and I were staying at a Holiday Inn in San Francisco.

I said, "Let's run around nude in the hallway making farting noises".

He went for it.

After a few seconds of these mindless antics I ran back into our room and locked the door, leaving him outside and naked. :D

After a few frantic knocks on the door I let him back in.

I should have left the door locked and asked, "Are you the naked male hooker that I ordered through room service?" :D


Another time my wife's mother left some annoying message on my voice mail.

I called my voice mail and paused on the start of her message.

Then I called my wife and conferenced her with her mother's message.

I really enjoyed listening to her argue with that recording. ;)

This happened when I was on my High School days.. here's how it happened. I have a rat rubber like with me.. when my teacher was facing the board writing something I called on my classmate *a guy friend* then I said *catch*
he was about to catch it but when he saw what it was, he shout and get off at his seat.. I was laughing so much because of that.. there was a rumor that he was a gay, and I think he is =D
