Tom Brady's "Boston Accent" Mocked, Is Mistaken for Matt Damon

Tom Brady is wicked mad.

In a new "Funny or Die" bit, the New England Patriots quarterback encounters a pushy salesman in a Los Angeles Dick's Sporting Goods who is convinced Brady speaks with a stereotypical Boston, Mass. accent.

As the sales associate calls customers over to "get a load of this Boston guy," Gisele Bundchen's hunky hubby, who stresses that he actually hails from San Mateo, Calif., begins to lose his cool as the crowd mocks his "accent" and fails to recognize him as the NFL Pro Bowl pick he is.

One patron even asks the 34-year-old athlete, "Are you Matt Damon?"

Watch the hilarious clip above to see Brady lose his cool!
