Some interesting information that I got from Wikipedia:
Gary Coleman is a character (not an actor) in the hit 2003 Broadway musical, Avenue Q, which won the 2004 Tony Award for best musical. The character works as the superintendent of the apartment complex where the musical takes place. In the song, "It Sucks to be Me", he laments his fate.
In the Broadway musical, Coleman states:
I'm Gary Coleman from TV's Diff'rent Strokes
I made a lot of money that got stolen by my folks
Now I'm broke, and I'm the butt of everyone's jokes
But I'm here - The superintendent! - On Avenue Q!
In the London production, Coleman's lyrics are:
I was the cutest little Black kid on TV
I made a zillion dollars that my parents stole from me
My life was over when I hit puberty
But I'm here - Fixing the toilets! - On Avenue Q!
In both versions, Coleman continues:
Try having people stopping you to ask you "What'chu talkin' 'bout, Willis?"
It gets old!
When the real Gary Coleman was asked his opinion on the Avenue Q character, he responded, "I wish there was a lawyer on Earth that would sue them for me."
