richard pryor, playing on sesame street

whose idea was this? i mean, seriously. who sat behind a desk and thought this one up? did it take a lot to get him to do it, or did he just breeze on through and rip it up? the late, great richard pryor, playing with the pre-k set while teaching them the alphabet - even if it's all the way through the tv set - is just flat-out brilliant. sesame street was light years ahead of its time.

hm. i wonder if he's high?
