Here's a blonde joke (because they are always so lame they're funny :D) Three girls go into a hippy store, a blonde, a red head and a brunette. While browsing, one of them spots a funny looking disk with glyphs carved on the surface. She picks it up and asks the shop assistant - "Hey, what's this?" The assistant says "It's an ancient form of lie detecting. If you tell the truth while holding it, nothing will happen. If you lie, well... you'll vanish." Intrigued, the three girls gather around it. The brunette decides to try it first, holding it in both hands she says "I think I'm the prettiest girl in school." Nothing happens... so she passes it to the red head. She holds it in front of her and says "I think I'm the smartest girl in school." Again, nothing happens. The blonde eagerly grabs the disk and says "I think-*POOF!*" and she vanishes.
