For the one person who still doesn’t understand the sports included in the Summer Olympics — so you’re that person?!? — BBC America has enlisted American comedian Dave Hill to help explain and demonstrate them.

Here he is on the parallel bars. And based on the U.S. men’s gymnastics team performance last night, perhaps they could have used Hill’s participation! Sigh.

But who is Dave Hill, exactly? He and BBC America have that covered, too.
