A lot of people have done their own take on Bob Sanders facts and they've all been awesome.  With that said, I'd like to throw my own contributions into this growing source of information about Mr. Half-Man, Half-Missile:

Bob Sanders makes Wilt Chamberlain look like the 40 Year Old Virgin.

• Only one player could even come remotely close to Bob's ability on the field.  Because of this he granted him the honor of playing the same position as him and wear the same number.  What was his name?  Sean Taylor.

• After failing to mimic his actions in a game of Simon Says, Bob put a curse on the violator that gave him the opposite qualities of Bob on the field.  Gilbert Gardner was never the same.

• Before his first football game, the trainer asked what size cup he needed.  He replied "Super-size me!"
• Colts games are not aired in Japan out of the fear that viewers will think that Bob is a scarier, more destructive version of Godzilla.
