The Big Jump

Q: OK, there's a smart blonde, a brunette, and Santa Claus on top of the Empire State Building. If they all jump off at the same time, who will hit the ground first?
A: The brunette, because the other two don't exist!

Appliance Store

A blonde woman walks into a store and asks the clerk about the TV in the corner. The clerk says, "Sorry ma'am, we don't serve blondes." Irritated, the woman goes home and dyes her hair black. The next day she comes back and asks again. The clerk again says, "Sorry ma'am, we don't serve blondes." Furious, the woman goes home and dyes her hair red this time. The next day she goes to the store and there's a different clerk there. She asks the clerk about the TV. The clerk replies, "Sorry ma'am, we don't serve blondes." The woman asks him, "How did you know I am a blonde?"  The clerk says, "Because that's not a TV, it's a microwave."

Library

A blonde walks into the library. She walks up to the counter, SLAMS a book down and screams at the librarian, "This is the WORST book I've ever read! It has NO plot and far too many characters!" The librarian looks up and calmly remarked, "So, you're the one who took our phone book!"
