Guest star Wally Boag is best known for his record-breaking performances at Disneyland's Golden Horseshoe (as Kermit mentions in his introduction). It was here that he gave some valuable comedic pointers to an aspiring entertainer who was, at the time, working in the Magic Shop on Main Street: Steve Martin! Martin himself was a guest star in season two of 'The Muppet Show' where he, like his mentor, Boag, also made balloon animals.
The "teeth" Wally Boag spits out are actually Lima beans.
Wally Boag recreated the "Pecos Bill" sketch which he performed at Disneyland. The song originates from Disney's animated version of Pecos Bill, which appeared in the feature film 'Melody Time.'
In late February, 2021, this became one of 18 Muppet Shows to get a content warning on Disney+, for "negative depictions and/or mistreatment of people or cultures".
