An overdone bagel has forced the evacuation of Portland's City Hall.

The Oregonian reports that City Hall emptied for about 20 minutes Wednesday morning while firefighters dealt with the burning bagel in the break room of Mayor Sam Adam's office. There's no immediate word on who burned the bagel in the toaster oven or what type of bagel it was.

City commissioners were meeting at the time and joined those who took to the sidewalks. Adams apologized for the interruption after the evacuation.
