KC Undercover 206 - Accidents Will Happen
Rick Fox will really guest star on just about any show, won't he? It took me awhile to recognize the voice, but he was the driver and ex-husband of Erica as they planned in the limousine.
This sibling rivalry is a fun multi-arc storyline and I really wish more shows, Disney Channel, or more adult, starting incorporating these kinds of plots. I think The Grinder is really the only other mainstream-esque comedy that is currently having a carryover storyline from episode to episode.
