Diff'rent Strokes star Gary Coleman is selling his US GameCube on eBay, and he has signed it with a pen.
His signature is also sprawled across the inclusive games Mario Kart Double Dash, Super Smash Bros. Melee, Robots, Mortal Kombat Deception, Sonic 2 Adventure Battle and Sonic Gems Collection.
According to the listing the GameCube has only been "gently used" in the past, and if "you love Gary Coleman!!!!!" you will stump up more than current highest bid USD 510 to win it.
Diff'rent Strokes was a US sitcom that ran from the late 70s to the mid 80s, and saw Coleman take the role of character Arnold Jackson and say "what'chu talkin' 'bout, Willis?" a lot.
The actor has a congenital kidney disease resulting in a tiny height of just 4' 11", so says Wikipedia I just thought he was small, and he also voiced Kenny Falmouth in The Curse of Monkey Island.
Mind you, if you wanted a GameCube for considerably cheaper you could search the whole of eBay and discover that they usually sell for about fifty quid with lots of games. They aren't famous, though.
