Painter's Doctor

And there was beeing a exposition for a famos painter in town.
The pictures were amazing, perfectly painted. But people
wouldn't buy it. The price was to high.
Almost on the end of the exposition. A men came in, and talked
to the assitent.
"Excuse me, is it true that after the artist dies, the painting
is wort much more?" the man asked.
"Why yes" the assitent said, "What can I do for you?"
"I will like to buy all of the paintings, please, here is a
check."
"Wow, thanks."
So the guy went away. With a smile on his face. An the
assistent ran to tell the artist the great news.
"What, he bought it all?" the artist asked. "Why?"
"I don't know, he asked if when the artist died, if the paings
were worth more." the assistent said "I told him that yes and he
bought it all"
"What's his name?"
"Dr. Hank" the assitant said taking a look at the check. "Isn't
that the doctor that checked you last week?"
