Sesame Street was Jim Henson's big break, and really got things going for the Muppets, but Henson was doing TV spots and commercials with Rowlf and Kermit quite a bit earlier. So they're sort of intertwined, but yeah, Sesame Street definitely showed up before the Muppets really found their spot.

Definitely watchable! I wish more kids' shows could do comedy half as well.
