It was Goodie Mob who once rapped: People don't dance no mo', all they do is dis. The "dis" they're referring to is head-nodding to the beat, arms crossed, unsmiling. It seems that everyone's too cool to make asses out of themselves on the dance floor these days. Well, people still do dance in some parts of town, particularly at the Peanut downtown on Sunday nights. The weekly "Hip-Hop and Hot Wings" event is attended religiously by regulars and enjoyed by newbies. There, in front of three sets of turntables, a circle forms around a mopped section of the bar's floor, and B-boys and B-girls do their thing. Different crews come and go, but there's always somebody there to entertain the crowd and challenge other dancers with top-notch footwork, top-rocking handstands and windmills. And when the mood is exactly right and the $2 well drinks have kicked in and the DJs have built the tracks to the perfect groove, bystanders forget to worry about getting kicked in the face and turn the B-boy circle into a real dance floor. If Cee-Lo Green came to Kansas City and visited the Peanut, he'd have to write a whole new song.
