My best chat up line was to draw a cartoon/ portrait of the girl. I am/was really good. Very rarely failed. I even once had some girl berate me for not phoning her up after drawing her. Believe me, it's better than any aftershave or haircut. Not as powerful as a fat wallet though...
Don't know why but that brought to mind the old joke............. What do you give the man that has everything.................Penicillin badoom tish.
