competition: the funniest joke ever!

there were a brunnette, a red-head, and a blonde who walked into a bar. in this bar there was a magic mirror and if you lied in front of it it would suck you in. so the brunette walked over to it and said "i think i am the prettiest woman in the world" and it sucked her in. the red-head said "i think i am the smartest woman in the world" and it sucked her in. the blonde said "i think" and it sucked her in. :)
