The teacher tells little johnny,
“I’m going to describe an animal and you have to guess what it is.”
“It lives on a farm and gives milk”
“A cow?”
“That’s correct too, but I meant a goat. “
“What lives on a farm, has feathers and lays eggs?”
“A chicken”
“That’s correct too but I meant a duck.”
Little Jack, getting annoyed, asks the teacher:
“What goes into your mouth hard, and comes out soft and wet?”
The teacher starts blushing.
“That’s correct too but I meant chewing gum.”
