Sonic the Hedgehog 2 Special Edition/YMMV

Non Sequitur Scene, The LP.
Ear Worm: The a cappella rendition of the original ending theme, complete with Word Salad Lyrics. Then again, it's by Demontomatodave, so it's a given.
Game Breaker: Knuckles is broken beyond belief, able to clear entire stages by just leaping into orbit and summoning the bazooka-toting police officer from Streets of Rage to One-Hit Kill bosses. Fortunately, there's a cheat code to Nerf him and make the game more fair.
Ho Yay: Sonic & Tails.
What Do You Mean It's Not Political?: No Blood For Oil Zone is widely believed to be an allegory for the first Gulf War.
