Former child star Gary Coleman, now 42 years old, is currently listed in critical condition at Utah Valley Regional Medical Center in Provo, Utah. No reason has been given for his hospitalization. This is the third time that Coleman, who suffers from a rare kidney disease that stunted his growth at an early age and forces him to undergo dialysis daily, has been in the hospital for an emergency since January.

For those of you who don’t know who Coleman is, he became famous as Arnold Drummond, a character in the 1970s-1980s sitcom Diff’rent Strokes. He’s best known for his classic line, “Whatchoo talkin’ ‘bout, Willis?”

Here’s hoping that the little guy pulls through.
