Celebrity chef Gordon Ramsay is used to TV appearances, but he's also used to swearing. A lot.
That's why family friendly late night host Jimmy Fallon had to put the 'Hell's Kitchen' star on the naughty step when he dropped the F bomb.
It was tricky for Ramsay to get to the naughty step because he's currently recovering from surgery on his Achilles tendon.
And the punishment didn't help, because Gordon slipped out a few more naughty words while he was there.
