One day, a primary school teacher was explaining the meaning of the word "乳" (rǔ) (breast, milk) which in this case the word "乳" could be used to describe little/small.The teacher wanted the Boy to use the word "乳" to make a sentence.

Boy : The price of property is very high, my family could only afford to own a 50 square meter breast. (乳房 means breast or b00bs but what the boy wanted to say is they can only afford a house that is 50 meter square)

Teacher sweat.gif : Please try again..

Boy : Im still a young boy, I could not even jump over a cleavage that is 1 meter long. (乳沟 means cleaverage.The boy was going to say he cant jump over the drain)

Teacher sweat.gif sweat.gif : Lets have another one.

Boy : Teacher,I really can't think of another sentence, I think my nipple is going to burst.(乳头,means nipple.The poor boy wants to say his head is going to burst.)
