Joke du jour: wayward daughters

Three women -- a brunette, a redhead, and a blonde -- are talking about their teenage daughters.
The brunette says, "Guess what? I found cigarettes in my daughter's room -- and I didn't even know she smokes!"
The redhead says "I can top that! I found a bottle of booze in my daughter's room -- and I didn't even know she drinks!"
Finally the blonde says "That's nothing! I found condoms in my daughter's room -- and I didn't even know she has a penis!"
