I recently was looking at videos on YouTube, and came across this clip of Krang talking.
It credited Pat Fraley as Krang's voice actor.
I thought "that doesn't sound right, he did Bravestarr from, well, Bravestarr, didn't he?"
Well, I checked Wikipedia, and he did do both voices. (I do recall that in the special features from the Best of Bravestarr disk that Fraley remarked he usually did villains.)
So yeah, that's pretty amusing.
