Kevin Smith, who is best known as Silent Bob in his "Clerks" movies, is silent no more.

The actor and director, who has battled his weight for years, is fuming after being kicked off a Southwest flight because he didn't fit comfortably in his seat, People magazine reports.

"You -- with the wrong sedentary processed-foods eater!" Smith posted on Twitter (@ThatKevinSmith). Smith's next film, "Cop Out," comes out Feb. 26.

Smith posted many tweets recounting his humiliating expulsion Saturday from the flight from Oakland to Burbank, Calif. In a statement, Southwest said airline officials had offered Smith their "heartfelt apologies," but that his removal was for the "safety and comfort of all customers."

Smith, 39, had purchased two tickets "as he's been known to do when traveling Southwest," the airline noted, but he then decided to fly standby on an earlier flight. Only one seat remained on that flight. Smith was asked to leave, even though he already had been seated.

"If a customer cannot comfortably lower the armrest and infringes on a portion of another seat, a customer seated adjacent would be very uncomfortable and a timely exit from the aircraft in the event of an emergency might be compromised if we allow a cramped, restricted seating arrangement," Southwest said.

"I know I'm fat," Smith said, but he was in no mood to accept an apology, or the $100 voucher he received. (He arrived in Burbank on a later flight.)

"I broke no regulation, offered no 'safety risk' (what, was I gonna roll on a fellow passenger?)" he tweeted. "I saw someone bigger than me on THAT flight! But I wasn't about to throw a fellow Fatty under the plane as I'm being profiled. But he & I made eye contact, & he was like 'Please don't tell . . . ' "

After landing in Burbank, Smith wrote, "Don't worry: wall of the plane was opened & I was airlifted out while Richard Simmons supervised."
