Yes, Muppet_dk's a great source for Muppet researchers like us. BTW: He said in the "News Flash: Ali Baba" thread in the Classic Sesame section that his hard drive had to be replaced, and thus he's lost some of the stuff he had saved. He's working on getting it replaced, either with what he lost or with new material.
Anyway, I remember the apple-walnut-raising cookies sketch and the #9 Special of the Day sketch.
I'll help you with the latter DanteCat. Mr. Johnson (Fat Blue) shows up at Charlie's for lunch as usual. Grover appears and proclaims that they have nine different specials for lunch that day. He then proceeds to read them off his list, including peanut butter and jelly sandwiches, the ever-popular "arroz con po-llo!", and the #9 special. Thinking it's some mystery dish, Mr. Johnson orders the #9 special. Grover goes into the back and comes out with a pinkish number 9 standing atop a bed of lettuce. Mr. Johnson then tells Grover to take it back.
Grover: "What?"
Mr. Johnson: "Well yes, you see, you didn't ask me how I wanted my number 9. And I prefer them well done, this one's medium rare. So take it back and bring me another number 9."
Grover then faints onto the floor, somewhat taken aback that his customer got the comedic drop on him for once.
Hope this helps and have a good weekend.
