Go Texans!

The photo at the top is of Muhammad Ali. It is one of the most iconic sports images of all-time. 

Neil Leifer's iconic photograph of the moment, in 1965, when Ali stood over Liston, shouting, 'get up and fight, sucker.'

The bottom image is of the NFL's best wide receiver, Andre Johnson.  The photo was taken after Johnson's game tying touchdown last Sunday against the Washington Redskins.
