Wow, he died later the same year he was on "Cheers"
I found the information below about Spanky:
Date of Death
30 June 1993, Grapevine, Texas, USA (heart attack)
Spanky's famous double and triple-takes were taught to him by Stan Laurel, while a lot of his mannerisms (rolling of eyes, hands on hips, and his trademark exasperated expression) were inspired by Oliver Hardy.
So far he is one of the only two members of "Our Gang"/"The Little Rascals" to be honored with a star on the Hollywood Walk of Fame,(co-star Jackie Cooper being the other one of the two).
