Same here - I still take a lot of stuff literally, and I end up going on a major-league guilt trip because of it.
Was just watching two FR episodes, both starring the Honorable R.H. Hunt: "Fraggle Wars" and "Junior Sells the Farm." Now, I have something to say about the song "Dream Girl Lover." I mean, Junior Gorg singing a Marvin Gaye-style love ballad with a slight hint of reggae...I'd be surprised if Richard was able to get through that song without cracking up completely.
On another topic (I'm jumping around a bit, I know), I learned another connection between Richard and his pal Mark Hamill. Among other things they have in common: Mark's middle name, according to Wikipedia, is Richard.
