So weird because growing up I always thought muppets = for adults and sesame street = for kids. Maybe that's just because sesame street was something I actively watched and the only reason I knew what muppets was was because my mom had some old muppets merch. It's strange but not surprising that soem group would get all up in arms about it though, especially since it was still just a ABC sitcom, so it's not like it was that vulgar.
