Apparently, wearing "tighty whiteys" is letting the terrorists win.
During a session in the Canadian Parliament, Pat Martin from Winnipeg left his seat on the floor during an important vote of anti-terrorist legislation.

When his vote was challenged by a member of an opposing party, Martin gave a hilariously epic explanation in which he blamed his purchase of cheap underwear. Apparently, they were creeping up the Great White North, making it uncomfortable to sit for long periods of time.

Martin stated, on the record, "I can blame it on a sale that was down at the Hudson's Bay [Company] – they had men's underwear on for half price. I bought a bunch that was clearly too small for me and I find it difficult to sit for any length of time. I apologize if it was necessary for me to leave my seat briefly, but I did not mean to forfeit my right to vote."

The house broke out in laughter and applause.
