When you think "NFL" and "joke," the Cleveland Browns usually come to mind, but these guys are doing their part to change that.

Whistle Sports has come out with this video in which NFL players take part in the "bad joke telling" challenge. The rules are simple: the first person to laugh loses.

And we should mention the jokes are about as bad as you can imagine, straight out of a book of yuk-yuks for first graders.

Here's a small sample:

What do you call a bear without any teeth? A gummy bear."

"What type of music do mummies listen to? Wrap music."

"What do you call a computer that sings? A Dell."

So, you get the gist, right? The jokes are so bad it's hard not to laugh.

Give the whole video a watch for yourself and just remember that it's nice to see football players smile after a season of grimacing intensity that plays out in stadiums across the country every Sunday.
