Crowning Moment of Awesome: For example, Greg is the kind of Cowardly Lion who you'd never meet in the bad part of Bed-Stuy. But, Greg had shown up to meet Chris and dissuaded Chris from going along with the plan of being a lookout. Had it not been for Greg's dissuasion and concern, Chris would have likely gone along with the plan of the cool kids and gotten into trouble. This is one of the few instances in which Greg actually helped Chris get out of a serious situation.
Another example is when Julius reveals to Rochelle the reason for having a credit card... and the reason (buying Rochelle's ring) promptly does something that Julius has never been able to do during their time together: shut her up.
"Funny Aneurysm" Moment: In the series finale, Chris' mother mocks Chris for trying to justify going for a GED by pointing out Bill Cosby got a GED because Bill Cosby was a comedian. In recent years, it's a pretty good thing she didn't want Chris to be like Bill Cosby.
