A man is moaning to his mate that he never has any luck with pulling women.
His mate tells him he has a chat up line that never fails, no matter how good looking the women are he always ends up in bed with them.
“Great, “says his mate, “what is it! ?”
“Just walk up to any woman you fancy and say, ‘Excuse me love, could I ask your opinion! Does this damp piece of cloth smell like chloroform to you?’ “
