The Graham Norton Show throws up an astonishing number of viral video clips. Some, such as Will Smith performing the theme from The Fresh Prince Of Bel-Air, are scripted, others, such as this one, most definitely are not.

This video shows a giant fly invading the studio while Norton is interviewing Steve Carell, Kristen Wiig, and Chris O’Dowd. As is to be expected with three comedians on the sofa, hilarity ensues.

Carell’s tip on how to kill flies is funny, but O’Dowd accidentally swallowing the fly, killing it in the process, before spitting it out into his hand, is even funnier.

There’s also a rumor going around that Wiig broke wind while laughing hard. Judge for yourself by listening hard at around the 1 minute, 47 seconds mark.
