You might know him as the man with a gazillion voices. His name is Brock Baker and doing impressions is his forte. Whoever and whatever character you can think of, this guy can probably do. So if you find yourself in a bit of a bind--like, say, when your girlfriend calls and you're out with some other chick--then having this guy around would be useful because he could pretend to be your mother and all.
Kidding aside, Brock's back with his latest impression medley where he does 33 impressions of different characters from the Simpsons in 5 minutes. The impressions are one thing, but the speed with which Brock can go from one voice to another is nothing short of impressive.
