Why have two children? Because extubation can be discussed.

A lady went to an art dealer to buy a painting. She picked up a still life painting, a bunch of flowers, a plate of ham and a bagel.

The lady asked, "How much is this?"

"Fifty dollars, very cheap."

"However, a painting I saw the other day is almost exactly the same as this one, and it only costs $25."

"Then it must not be as good as this painting." The art dealer said very skillfully.

"No, I think it's better than this."

"Why?"

"There are more hams in the saucer in that picture than in this one."
