A friend of mine got me, and some others with this prank. He took some black Ink and put It on a pair of Binoculars, so after I looked thru them, I now had these black circles around my eyes. Those fuckers let me walk around for ten minutes before I realized what they did.
My revenge... I took a big piece of white cardboard and wrote on It... I'm Gay, and proud of It... Honk If you support Gay pride.
I taped the cardboard on the tailgate of his truck, on his drive home he had several cars pass him on the freeway blowing their horn and laughing at him.
Another favorite of mine Is to take some of that packaging bubblewrap and tape It to the top of a car or truck tire, when they start to drive away, POP.. It scares the shit out of them, But no harm done.
