"I heard there's a book out that says Hugh Hefner has had two thousand women in twenty years," Matthau said.
"Two thousand?" said Burns.
"That's right."
"That works out to one thousand girls every ten years."
"That's right."
"A hundred girls a year. A different girl every three or four nights." He studied his cigar.
"Hefner has to be a very unhappy man," Matthau said.
"That's easy, that many girls," Burns said. "It's easy to do with two thousand different girls. What's hard is two thousand times with your wife."
