Chet and Snooks

Chet and Snooks are a duo of vaudeville-like Anything Muppets who one day randomly pass through Don Music's studio while he and Kermit are trying to figure out the next letter in The Alphabet Song. Snooks asks Chet if he knows why the fireman wears red suspenders and Chet eagerly tells him to say WHY, which causes Don to remember Y|which letter he's looking for. A minute later, they reappear with the rest of the company to join in the song.
