Actually, the voices on McDownTrends and the spam rants - that was all me! I'm too poor to hire voice artists any more, they're freakin' expensive usually — some of those turkeys make mad cash! XD
But... those silly voices (and others) over the years have been a good starting point...
Graphics/animation is so much of a hassle... constantly having to stay up on complicated and expensive hardware/software... Whereas once the initial equipment is purchased for voice work, that's pretty much it... Sure, there's always stuff to learn, but it's not like the fever-dream of super techy software :D
