Most people learn what a synonym is before they turn 10. They're given a word and asked to find another word that has a similar meaning. And then, they're forced to do this over and over and over again until they fully grasp what is a synonym is.

It seems Jon Gruden must have been absent the week that his class went over synonyms, though. Because while he's 51 now, he admitted that he just learned what a synonym is on Monday Night Football last night. And Mike Tirico found it absolutely hilarious.

Listen to Gruden talks about synonyms in the clip above. Was he serious?!
