Kevin SmithKevin Smith is not a happy Southwest customer.

The director was thrown off a flight from Oakland to Burbank, after being deemed too fat to fly. He would later end up on another Southwest flight and now he's expressing his anger on Twitter.

"Dear @SouthwestAir - I know I'm fat, but was Captain Leysath really justified in throwing me off a flight for which I was already seated?" her began.

"Dear @SouthwestAir, I flew out in one seat, but right after issuing me a standby ticket, Oakland Southwest attendant Suzanne (wouldn't give last name) told me Captain Leysath deemed me a "safety risk". Again: I'm way fat... But I'm not THERE just yet. But if I am, why wait til my bag is up, and I'm seated WITH ARM RESTS DOWN. In front of a packed plane with a bunch of folks who'd already I.d.ed me as 'Silent Bob,'" Smith continued in a succession of several tweets.

Smith even posted a photo of himself on the plane.
