Dale: The great Daledini sees all, and knows nothing!
Chip: You got that right, acorn-brain!
Nimnul: They laughed at me at the invention convention! Called me mad! Hah! Mad, me? A little angry maybe, but not mad!
We see another demonstration of Chip's loyalty to the others in this episode. Nimnul's device is about to explode and it appears that only Chip and Zipper have time to escape - instead, Chip elects to stay (and possibly die) with his friends
Nimnul: Let's get Physical!
This is a reference to the song "Physical", by Olivia Newton-John.
Prof. Nimnul: ...Or dare I say it, Mr. Potato Head!
Mr. Potato Head was a wildly popular children's toy. His appearance was of a potato with removable facial features that could be inserted anywhere on him. Ironically, he was later featured as a character in the "Toy Story" movies.
Dale: I knew this case was gonna be a Thriller!
Moonwalk Jackson, whom Dale refers to, is an obvious parody of the singer known as Michael Jackson. Dale even uses the name of one of Jackson's songs, "Thriller", while doing the dance featured in the song's music video.
