Ashton Kutcher's unsavoury digital short filmed for his appearance on Saturday Night Live at the weekend (06Feb10) has hit the Internet.

Ashton Kutcher's hilarious 'ad' for Twitter.com offshoot 'Tooter' failed to make it on the sketch show, but the actor is so pleased with it he's linking to it via his blog site.

In the bogus ad, Ashton Kutcher creates a Twitter-type initiative to give fans the sound and smell of his own flatulence.

The skit also features rockers Them Crooked Vultures and a very disapproving Questlove from The Roots.
