When Robert started going out with his police partner (Sherri Shepherd) to the clubs she frequented and he started to adopt their style of dress and way of speaking.
He walked into Raymond's house with his new bright gold "fly" suit on and told Raymond "Ya gotta get out more my brother". 
He began dancing in the club and everyone gathered around him yelling "go Robert, go Robert" and he'd just be dancing away with his tall self having a great time.
Lots of good episodes with this sitcom.
