I dare you not to laugh at this Comic Relief skit starring Robin Williams, Whoopi Goldberg, and Billy Crystal.

Comic Relief America was a very big deal back in the day. Aside from raising funds for the needy, particularly the homeless, the charity event starred three of the greatest comedians of all-time: Billy Crystal, Robin Williams and Whoopi Goldberg. Each year the trio would come together to film a special for HBO and support worthy charities while making audiences laugh.

Any of the specials and clips are worth your time, but this one in particular always makes me laugh until my sides hurt. In the clip below, Crystal tries his absolute hardest to finish an introduction for an upcoming segment while Williams tries his absolute hardest to derail his co-star. It’s unclear if the interruptions are intentional or if Williams, the reigning king of spontaneous comedy, just couldn’t help himself. Regardless, the result is 100% hilarious!

The clip below is about 10 minutes long but trust me, you’ll love every second of it:
