Don't Tell Her It's Me

A suicidal cartoonist suffering from Hodgkin's, who resembles Uncle Fester, meets a woman and has to pretend he's Kiwi Michael Bolton to impress her. The jokes just write themselves, folks.

My name is Lobo. I need no one. I hunt alone.

A We Hate Movies episode

I barely remember this so I looked it up: "Gus Kubicek is a depressed and overweight cartoonist who recently won a battle against Hodgkin's disease. His caring sister Lizzie Pots , a nosy romance novelist, responds to his sadness by trying to set him up with a suitable woman. Yet to do so she must make him seem more dynamic and attractive. When Gus falls in love with Emily, he adopts the persona of Lobo Marunga, a leather-clad biker from New Zealand.(wikipedia)" - Well that seems reasonable.
