This person GiIvaSunner takes video game music and edits them to be hilarious. Half of them are just edited to sound like the Flintones theme but it's somehow still funny.
Weirdly he posts like 20 videos a day and they are all really high quality.
This one is Pokemon/Flintones/Rich Girl by Gwen Stefani, and it still somehow ends up as legitimately good music.
This one requires no explanation.
This is the single most frustrating song you will ever hear.
