Usher, wearing a furry hat that rivaled what Pharrell Williams wore to the Grammys, teamed up with 'Tonight Show' host Jimmy Fallon (Feb. 24) to play a friendly game of 'Catchphrase' with actress Reese Witherspoon (and her lovely asymmetrical bob) and Olympian Mikaela Shiffrin.

For the game, you basically guess words from clues. Witherspoon was hilarious. When she given clues for "long johns," she said "G-string!" And when she had to give clues for "Germany," she said it was a country in Europe that speaks a foreign language. She was so cute when under pressure.

Usher and J. Fal took the game, though, as they were a bit more calm and collected.

It was silly and tense!
