2k3 Mikey started vaguely annoying, pulling out an occasional joke that did land, but as the show went on he became very mean spirited, completely unfunny and unbearable.

And that was just his personality. His voice started to become grating as well, to the point where by the time Back to the Sewer began, he seemed to almost scream practically every line he had, didn't seem to care about anyone else and pretty much gave up on jokes and just annoyed people.
