They left off "Die Hard." It's only August, but this is already a clear favorite for Worst Movie of the Year. Neal Brennan's comedy about a crack team of car salesmen sure isn't funny. In fact, its real value is probably as a study in how to blow every possible comic opportunity. I see important lessons in: substituting "fuck!" for a punchline; making lame in-jokes (calling Albuquerque "Kirkie"); being racist, sexist and homophobic (just being obnoxious isn't an automatic laugh-getter); and hiring Jeremy Piven, whose same-old schtick is well past its freshness date. Don't be lured by the fact that a lot of your TV favorite funnymen (Rob Riggle, David Koechner, Ed Helms, Craig Robinson) got belted into this lemon: They can't save it, and why should you pay to see their shame?
