Jackson was appearing on 'What Up' to promote his charitable foundation but 'host' Kenan Thompson kept interrupting him with musical numbers.
“Don’t you dare cut me off! F**k!"Jackson, playing a pitch perfect caricature of himself, finally yelled.
The camera immediately went to the fabulous Thompson, who almost lost it. "Come on Sam, that costs money," he laughed, a reference to a possible FCC fine.
NBC has since muted the offending word, but Jackson is having fun with it. "I only said FUH not F--K! K was sposed to cut off da BULLSHIT, blew it!!” he tweeted after the show.
Either way, you can watch it here!
