Jeff Conaway, the star of Grease and VH1's Celebrity Rehab, is hardcore. Sometimes people, like the Gallagher brothers, don't realize when you are super hardcore so they need to be threatened like only a true Greaser pimp can.

The ungrateful twits, Noel and Liam Gallagher from Oasis, were backstage at a Marilyn Manson show in Los Angeles. The brothers were doing what they do best besides fighting, drinking absinthe. They were interrupted by Jeff who wheeled up on them in a wheelchair.

Noel recounts the story:

"Conaway shouted, 'I've had four back operations, you know.' So I said 'So get yourself out of that wheelchair then!' He said ' I've had four operations but I can still pull a knife on you.' And he pulled out a big blade."
