Three men were talking about their teenage daughters.

The first says "I was cleaning my daughter's room the other day and found a packet of cigarettes. I didn't even know she smoked".

The second says "That's nothing. I was cleaning my daughter's room the other day when I came across a full bottle of Vodka. I was really shocked as I didn't even know she drank".

Then the third speaks up. "Both of you have got nothing to worry about. I was cleaning my daughter's room the other day and I found a packet of condoms. I was really shocked. I didn't even know she had a penis".
