The Many Accents of Matthew

Matthew has been demonstrating a variety of accents lately. Some, I have no idea where he's picking up. Others have a direct source:

British: When Matthew talks about his favorite Wallace and Gromit movie, he calls the character Victor Quartermaine "Vict-ah."

Southern: Granted, I may have influenced him a tad. Matthew makes random one syllable words into two-syllable words. For example, hat becomes ha-at.

Canadian: Just tonight, Matt was saying (repeatedly), "That's what I'm talking aboot!" No idea where that one came from.
