But that's nothing compared to Lohan's other completed project, an appearance in Underground Comedy 2010 — a film proudly promoted as "the single most offensive movie you'll ever see" — written, directed, financed by and starring Vince "The ShamWow Guy" Shlomi.

Shlomi, who goes by Vince Offer in the movie, is better known to late-night television viewers as the infomercial pitchman behind the super-absorbent ShamWow and the Slap Chop kitchen gadget. He has been trying to break into the movie business for a while on the strength of Underground Comedy — a collection of tasteless sketches he's been working on since 1996 that was released briefly to horrified mainstream reviews in 1999 (The New York Times referred to the film as "wretched").

Lohan's segment of the film — in which she acts out a celebrity revenge fantasy, shooting up a gaggle of paparazzi while dressed like Marilyn Monroe — is tame compared to the movie's other sketches, which include scenes of an infant being shot in a drive-by and a necrophiliac sexing it up with rotting corpses. But its very existence is a sobering reminder about how far the star of Freaky Friday and Mean Girls has fallen. Even Shlomi acknowledges he wouldn't have had a chance to get her at the height of her game. "Ten years ago she's doing Disney, and now she's in the most offensive movie ever made," he tells TIME.
