Plexiglas

Plexiglas is a term that means, essentially, "Let's do the same thing over," or, "Run it back again," even though the previous incarnation was likely lopsided or dissatisfying. The term originates from a story about snowlerbladers family dog. The dog was adopted after suffering some brain damage, and thus was not the brightest creature. The blader family boys figured out that when a piece of food was placed behind a sheet of plexiglas, the dog would run into it repeatedly, rather than just going around the side.
