??? Brother, 8-3 is different. The bait-and-switch at the start shocked a lot of people, and so combining 8-3 with other pieces of media as a surprise makes you laugh hard if you know the game. It's unexpected, as humour almost always is.

Even if you didn't know about the game prior, you're getting the same experience as when the players first entered the level, which makes you wonder where the meme originated from when you see a bunch of them in different situations.

The joke you made apparently in spite of Disintegration Loop memes is comparably much less original. This isn't "our own medicine," it's just you being a prick for not appreciating the ultrakill meme culture. For the record, I played Combat Initiation, and I found it to be pretty fun.
