Paris Hilton's day just went from bad to worse. While her lawyer is probably stressing out on how to keep Paris out of jail, her $450,000 Mercedes-Benz McLaren SLR was towed this morning because she did not fulfill her duties to promote a nightclub. This is the second club gig she has flaked on, the first being Club Paris in Florida. What else does Paris have going on besides shopping and partying that she can't fulfill her duties? What did she have to do besides show up?
