When we were kids, my cousin and I bought little explosives to put in his mother's cigarettes, but while we were testing them beforehand, they exploded in our faces. So I guess the joke was on us.
High school student
I was once given a soap dispenser that was shaped like a nose and it squirted out green soap.
I bought one of my fraternity brothers a pair of "Truck Nutz." They were like $30 plus international shipping, but the look on his face when he opened the package was totally priceless. He is still driving around with them hanging from the back of his car.
Someone once gave me a package of a variety of different kinds of dried fish that they brought home from a trip to China. It has become something of a legend, because I re-gifted it as a gag gift for someone else, and then she re-gifted it, and so on and so on.
While on a family trip once, I bought my mom an envelope that said "rattlesnake eggs" on it. When she opened the envelope to remove the card, the card made a rattling sound. She's never been quite the same since.
