Here's a familiar formula: stand up comedian + television cameras = sitcom. And, ultimately, that's the math behind HBO's new series " Crashing " starring Pete Holmes and executive produced by Judd Apatow . This show is a little different, though, from things like "Louie" and "Seinfeld" (and a lot different from things like "Roseanne" and "Everybody Loves Raymond") in that it's actually about Holmes's (character's) fledgling stand up career.
