When Grating falls onto Pete, the latter yells, "You are fired!"
The next moment, an elevator falls onto Pete, Wild Man Wyatt comes out and tells Grating, "You are dead!"
This line (approximately two seconds of the video) was cut out when the episode aired on Toon Disney.
The first toon we see at the territory of Wackytoon Studios is Dumbo, the flying elephant from the 1941 Disney cartoon of the same name.
At Wackytoons Grating meets Goofy and Pete (Goof Troop
). On seeing Grating at the set, Pete notes that he "thought this was a Donald Duck picture". Donald himself does not appear, but his portrait can be seen at the entrance to Stage 10.
The hippopotamus ballerina that dances with Grating is Hyacinth Hippo from Disney's Fantasia (1940). The alligator is Ben Ali Gator from the same cartoon.
