A mother is having a bath and her young son walks into the bathroom, stares at her and then points to her pubic hair
"What's that?"he asks
"My sponge " his mother replied
Next time she's in the bath her son comes in, points and says "I can see your sponge"
The mother is slightly embarrassed now and decides to shave all her pubic hair off
Next time she's in the bath her son comes in, points and says "Where's your sponge?"
His mum replied "I've lost it"
He leaves the bathroom and just as she's drying herself, the boy bursts back through the door shouting "mum, mum I've found your sponge"
"Oh yes" she replied "where is it?"
"Mrs Smith next door is washing Dad's face with it"
