The Blond Artist?

Wanting a portrait with which to surprise his wife, a businessman asked a blonde female painter he'd been recommended to paint him in the nude.

"No," the talented blonde artist said. "I don"t do that sort of thing."

"But what if I double your fee?" he pleaded.

"Nope, sorry. Won't do it."

"How about I give you five times what you normally get?"

"Oh, okay then," said the artist, "but I'm keeping my socks on. I need a place to put my brushes."
