Sourdough Sam

Sourdough Sam is a mascot for the NFL's San Francisco 49ers. According to his official biography, he has six nicknames: Sam, Sammy, Samster, Sammiester, Samarama, and Samalamadingdong.

Just prior to the 2006 NFL Season, Sam's appearance was altered somewhat. He used to appear as a character with a scruffy brown beard, brown eyes, and a wide-brimmed ten-gallon hat with a chunk taken out of its brim. He now appears as a clean-shaven gold panner with blue eyes and a hat without any imperfections.

He originated as the team's logo from 1946-62, where a prospector was depicted shooting two pistols and jumping in the air.

Outside appearances
He has appeared on FOX, Monday Night Football, ESPN's SportsCenter, Extra, MTV, Evening Magazine, and Nickelodeon.
