I loved this kid. He played Timmy (the former doll) on one of the 2 soap operas I watch occasionally ("Passions") and was young Grinch on How the Grinch Stole Christmas with Jim Carrey. (I think that is what it was called...)
Anyway, he was a midget and had a congenital heart defect. He was in the hospital the other night for a routine surgery (I believe) and died. Very sad.
Oh, and his character on Passions died the same day. That scene had been taped several months before... Very freaky & sad.
