It could have been the most controversial point of an action packed live 30 Rock show which featured appearances from Paul McCartney, Kim Kardashian and Danny Glover.
But despite his afro wig, dungarees and burnt cork-face, Jon Hamm managed to pull in a few laughs in a sketch which poked fun at 1950s American racial stereotypes last night.
The Mad Men actor appeared alongside a scornful Tracy Morgan in the flashback scene in a spoof of 1950s U.S. comedy Amos ‘n’ Andy.
Poking fun: Jon Hamm appeared in an afro wig and ‘black face’ as ‘Amos’ in a parody of a 1950s sitcom on last night’s live edition of 30 Rock
Hamm strode in wearing scruffy dungarees over a baggy shirt, appearing as Morgan’s brother in a flashback which was introduced by NBC page Kenneth, played by Jack McBrayer.

A second sketch then showed Hamm ‘hamming it up’ with a southern accent and holding a fish, declaring: ‘I just stoned this catfish.’
Morgan responded: ‘Stop talking like that,’ but Hamm paid no attention, declaring: ‘Zippidedoodoo.’
This led the enraged Morgan to attack Hamm with a chair. ‘I’m killing you, you ignorant…’
