While school is a place to enrich your mind and is definitely something that should be taken seriously, there's always that class clown who can't help but offer hilarious distractions to teachers and students. There are plenty of goofballs in the pop music biz as well, and we want to know who gets your vote for Class Clown of 2013 in PopCrush's Yearbook Superlative poll!

You can see some pictures of our Class Clown nominees below, and some are definitely more unexpected than others. For instance, you don't really associate Adele with laughing and much as crying (the tracks on '21' and '19' are enough to make a grown man bawl), but this cheeky Brit has one amazing sense of humor. Ed Sheeran is also kind of unexpected, as his music is on the more serious side, but the fun-loving, easy-going redhead is always great to lend a laugh.

On the other hand, we've got some pop stars who could become comedians if their music careers end up failing. Bruno Mars, Big Time Rush member Carlos Pena Jr., Jay McGuiness of the Wanted, Jessie J, Justin Timberlake, Katy Perry, Kesha, Macklemore and Olly Murs have all shown off their penchant for hilarity during their stage performances, in amazingly funny music videos, on comedic TV shows like 'SNL' and sometimes even in their songs!

So, which of these pop stars has made you laugh the hardest in the past? Cast your vote for Class Clown of 2013 below, and remember you can vote once per hour until the poll closes on Friday, June 21 at 12PM ET. Good luck!
