Brick Tamland, 'Anchorman: The Legend of Ron Burgundy' (2004)
Doctors claim that Brick Tamland has an IQ of 48 and is what some people might call severely mentally challenged. Maybe it's true, but frankly, it's hard to put anyone else in whatever psychological category he's carved out for himself. This is a person who introduces himself by professing his love for slacks. When he hears loud noises, he'll join in by screaming, "loud noises!" He once murdered a man with a trident. Somehow, he became a weatherman, obsessed with sunny San Francisco and referring to the Midwest as the "Middle East." Being a loyal colleague of Ron Burgundy has likely diminished what was left of Brick's intelligence. This is a man who was shocked to learn that baby pandas don't come from storks (they come from mother pandas — a miracle he witnessed first hand). Brick is in a class of his own— the posterboy for guys who love lamp, a walking, talking non sequitur, and the dumbest character ever committed to screen.
