A flat chested young woman goes out looking for a new bra one day.

She tries shop after shop trying to find a size 28A yet she can't get one anywhere.

Finally, in desperation, she tries her fortunes in a little unmentionables shop run by an woman who's hard of hearing.

"Have you got anything in size 28A?" asks the young woman.

"What was that, dear?" says the old woman.

The young woman repeats herself again.

Still the old woman can't hear her, so the young woman lifts up her T-shirt baring her breasts and says, "Have you got anything for these?"

The old woman peers at the woman's boobs and says, "No, dear. Have you tried Clearasil?"
