"Painting Nude" joke

A man requested a blonde painter to paint him in the nude.

"No" the talented blonde artist said. "I don't do that sort of thing.

"I'll increase your fee two times," he said.

"No, no thanks!!"

"I'll give five times as much as you normally get."

"Okay," said the artist, "But you have to let me at least wear my socks. I need somewhere to place my brushes."
