Fathers are talking about their teenage daughters

A group of fathers is sitting around talking about their teenage daughters.
One dad says, " I think my 16-year-old is smoking; I found an empty cigarette pack under her bed."
All the other fathers say in unison, "Oh no!"
Then a second dad says, "That's nothing. I found an empty liquor bottle under my 16-year-old's bed."
All the other fathers say in unison, "Oh dear!"
Then a third dad says, "Mine's worse than both of those combined: I went into my 16-year-old daughter's room and found a used condom."
All the other fathers say in unison, "Jesus Christ!"
The third father replies "Yeah, I didn't know she had a dick!"
