Upon exiting that scene, the plot continues on like it never happened. This is a very bizarre scene in an otherwise normal story that veers off into the surreal or strange. Springboarding from there, we find the Big-Lipped Alligator Moment, or BLAM ( an appropriate term in and of itself, as they tend to show up with all the subtlety of a shotgun blast). They have no actual bearing on the plot, although they are staples of characters who are part of their own little world like the Cloudcuckoolander or The Ditz.

A Non Sequitur is a bit or line of dialogue that is intentionally out of place, usually designed to elicit a comedic reaction.
