Alcohol
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".
