Here's how it really went down....

Mark and Tony were drinking at the bar one night.

Tony: "you should see some of the money people splash around for some of the *beep* paintings at my gallery"

Mark: "Yeh my daughter could paint better than half those jerks"

Tony: "You know what, we'll get Marla to make some painings, touch them up a bit so they look arty enough and sell them for thousands"

Mark: "Yeh, lets do it"

Mark goes back to Tony's house for gay sex

....so the scam begins
