Who says Jay Cutler doesn't have a sense of humor?

The Chicago Bears quarterback, sometimes maligned for his grumpy attitude, showed a softer side with a costume he sported for his 30th birthday party.

Cutler's fiancee, Kristin Cavallari, tweeted a photo of the two before Cutler's birthday party over the weekend. The party had an 80s theme, so there is no shortage of neon and long hair. But Cutler added an extra, important detail: a flimsy cigarette hanging out of the side of his mouth. The prop is a reference to the extremely popular "Smokin' Jay Cutler" meme, in which the quarterback has a cigarette dangling from his lips.

When the "Smokin' Jay Cutler" photos went viral, Cutler said he "got a kick out of the meme."

But not to worry, Bears fans. Cutler, who turns 30 on April 29, has not actually picked up the bad habit.
