The guy that voiced Cespenar (little imp butler in Balder's Gate II: Throne of Bhaal that can make items for you. "Stands back now! Coulds be messy!") also voiced Johnny Bravo (kind of blew my mind). However, he also voiced Illidan Stormrage in WoW and that completely blows my mind.
Cespenar - about 1:30 is the line I remember best (and got a little wrong in my quote up there) http://www.youtube.com/watch?v=svXzBG2RipA
Johnny Bravo - http://www.youtube.com/watch?v=WE3d2GHBuvQ
Illidan (took forever to find this and you have to turn the sound WAY up to hear it, but it's all there. Weeeee! Brings back memories. "I remain... unconvinced.")
Edit: Oh, right. Voice actor's name is Jeff Bennentt
