An Irish daughter says "my hands are freezing cold".
Her mum replies "put them between your legs"
So she does and warms them up.
Next day she's out with her boyfriend. He says"my hands are freezing"
so she says "put them between my legs, my body will warm them"
Then he says "my penis is frozen"
Later the daughter asks her mum "have you ever heard of a penis?"
Mum says "yes. Why?"
Daughter says " they make a terrible mess when they defrost don't they?"
