These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Wasted Songs: For those who are having a hard time finding all of them, they're all pretty much uploaded on YouTube. Sadly with the sole exception of The Flint River Band's "Wait and Break My Heart Tomorrow".
Special Effect Failure: Mac frequently makes the sound of wheels moving whenever he moves, and then there's Eric falling into the river (where he turns into a completely immobile and obvious dummy), a scene Paul Rudd frequently showed on Late Night With Conan O'Brien.
