British, Scottish, Irish, Italian and Greek accents seem to come second nature to me. I perform weekly children shows and am required to use many of these voices regularly.
Over the years I have managed to imitate accurately nearly all of the family guy, and Simpson cast. Including singing some of the popular songs, just as performed by the professionals.
FAMILY GUY: Peter Griffin, Chris Griffin, Brian, Stewie, Quagmire, Joe, Cleveland, neighbors, friends and most of the cast of Cleveland show also.
SIMPSONS: Mayor Quimby, Chief Wigum, Mr.Burns, Smithers, Disco Stu, Comic book guy, and many more.
Spongebob Squarepants and most of that cast as well: Mr.Krabs, Patrick, Spongebob, Squidword and more.
As a stand up comedian my act includes many character impressions of actors such as:
Jack Nicholson, Keanu Reeves, Patrick Stewart, Arnold Schwarzenegger, sylvester Stallone, Jimmy Stewart, Jim Carrey, Robert DeNiro, Jeff Goldblum, Christopher Walken, and many more.
