For those of you who just can't wait until the weekend to wait in line, today Super Duper Burger will give away free hamburgers today at all of its seven locations. Why? Why not.

Anna Roth has the details: "The first 100 people in line at each location at 3 p.m. will receive a free mini burger, aka a four-ounce Niman Ranch patty topped with cheese, lettuce, tomato, onions, and Super sauce."

Super Duper's S.F. locations are as follows:

Castro (2304 Market)
downtown (721 Market)
Metreon (783 Mission)
Embarcadero (98 Mission)
The Marina (2201 Chestnut Street)
