For this Photo-caption Extravaganza we'd like to know what is making perennial Pro Bowlers Lance Briggs and Brian Urlacher guffaw with such unadulterated exuberance. Is it a joke at the expense of one of their teammates, a joke about the Lions, Packers, or Vikings? What ever it is it better be damn funny, because it looks like Urlacher is doing the 'Happy Dance'.

Here are the rules; We want to know who is telling the funny quip, and to make it even harder, no mention of current or former Bears coaches allowed.

Remember to Rec your favorites, and the winner will have their caption inserted into the actual caption for all eternity. Or until SBNation removes the picture, which ever comes first.
