Jimmy Fallon allows a lot of things on The Tonight Show, but he doesn’t allow cursing. That is something Gordon Ramsay doesn’t know how to not to do, so when he used the F-word the NBC host sent him banished him to the naughty step.
Then when The Chef was ready to continue on with the interview, he hopped on back to he couch.
Did the naughty step teach him not to use 4-letter words? Hell no, and that is why we love the MasterChef.
