In the space of the last few weeks we have seen Twitter misused by Vodafone employees, when the firm went after 'beaver', a Labour MP forced to apologise for comparing pigs to the Conservative party, and now a fat man argue that although he is fat, he's not that fat. And get an apology for anyone suggesting that he was in the first place.

The rotunda in question was film director Kevin Smith, who has made one great film, and um, some others. Smith had been asked by a pilot to leave a flight because he was too large for the seat and its belt and would therefore pose a danger. Rather than go away and consider this in quiet dignity, he tweeted about it, and then retweeted about it, and so on.

His last comment on the subject, after a faltering apology from the airline in question, suggests that he is tired of talking about the whole thing - maybe he needs some sugar, and is just glad to be back on the footing that people accept him as being fat, but not that fat.

"Once again: I know I'm fat. The point of all this? I'm not too fat for Southwest Air, yet someone deemed me so. *sigh*," he wrote, making us wonder whether he regrets saying anything about it in the first place.

Well, he doesn't. Smith is insisting that Southwest release a statement in which it acknowledges that he is not too fat - you couldn't make this up - and adds, "Get me a document to sign, and I'll swear on my child's life and penalty of all I own that I'll never sue your Airlines. But just PUT THE F**KING TRUTH OUT THERE THAT I'M NOT TOO FAT TO FLY, AND THAT THIS WAS ALL AN UNFORTUNATE ERROR ON SOUTHWESTERN'S PART."

Whatever happened to fat people being jolly?
