I got another one...

If theres some Family Guy watchers over here

Seth MacFarlane (creator) voices Peter, Brian (which is his regular voice), Stewie, Quagmire, Tom Tucker, Carter Pewterschmids and some other random characters.

Alex Borstein voices Lois, Trisha Takanawa, Diane Simmons, Bonnie Swanson, Barbara Pewtershmidt and other randoms.

Mike Henry voices Cleveland Brown, Herbert, The greased-up deaf guy, and some more.

Its amazing how they all jump from one to another.
