No caption, I'm afraid, but saw this in JB, which may be apposite:
A bloke picks up a good looking woman in a night club. They move to the dance floor and start smooching. Now that he's close he can really smell her perfume.
"You smell really nice" he says.
"Oh, thank you", she replies. "Its Channel No 5".
"Mmm", she says "You smell pretty good too. What have you got on?"
"Actually", he replies "I've got a hard on, but I'm bloody surprised you can smell that!"
