That shirtless Super Bowl halftime show performance is the gift that keeps on giving.

It's called the Adam Levine challenge, and it all sprouted from Maroon 5's Super Bowl performance on Sunday night. Apparently, a lot of people didn't know that Adam Levine has a ton of tattoos; one of them being his home state of California.

So, Facebook user Daisy Delaney started the Adam Levine Challenge, which is supposed to highlight "normal" folks from all over the country.

She started out with the ladies...

...and then moved on to the guys.

The guys' response was so overwhelming that she actually started its own Facebook page.

Glad that she found a way to have fun with this! But I'm still not sending in a pic of my gut. ;) Kudos to everybody who had the cajones to do it!
