Little Johnny's mother is taking a bath, having recently been discharged from hospital where she had all her pubic hair removed. Johnny comes into the bathroom as she's drying off and asks her what happened to the hair.
"I've lost my sponge" she replies and sends Johnny out to play. A few moments later, Johnny returns and tells his mother he think she's found her sponge "Oh really," his mum asks Where is it?" Johnny answers, "The lady next door is washing daddies face with it"
