It’s a hot summer’s day and Rabbi Landau is walking with his pupils on Minnis Bay beach when a beautiful young girl in a swimming suit walks towards them.  Rabbi Landau immediately says to them, "Don’t look, boys, turn away your eyes."  Over the next 10 minutes, many young girls in their swimsuits walk past them and each time Rabbi Landau says to his pupils, "don’t look, don’t look.  Avert your eyes."

But then a gorgeous girl comes into sight wearing the skimpiest of bikinis.  She also has a voluptuous figure.  Rabbi Landau just can’t take his eyes off her as she walks towards them.

The pupils are very confused with the rabbi’s behaviour, so they go to him and ask, "Rabbi, you told us earlier not to look at the girls in their swimming suits, but just now, as soon as the girl in the bikini came into sight, you looked at her and haven’t stopped looking at her.  You haven’t even told us not to look at her.  Why is this rabbi?  We’re confused.  Is it right or is it wrong to look at girls?"

"It depends on the girl, my boys," replies Rabbi Landau, smiling.  "That girl is 100% kosher because the milchedik (he points to her bikini top) is very clearly separate from the flayshedik (he points to her bikini bottom.)"
