iteachvader has recently unlisted his YTPs, but they can still be found on these playlists here and here. His older CD-i-based YTPs feature some of the best sentence mixing you'll ever hear, while his Robotnik YTPs are a fantastic throw-back to greats like Boogidyboo and thechairman45.
There were a couple more I wanted to add, including a personal favorite called The Ozard of Wiz (there's a video with a similar name, but it's a different ytp), unfortunately it looks like youtube has taken them down due to copyright.
Fuck the people running youtube with cacti covered in hot sauce.
My friend was quoting this scene the other day and I felt like it deserved a good, short, nothing-but-ear-blasting-volume youtube poop. Mostly inspired by dew.
