You can't tell from this screencap just how close the Sun and Mercury appear to be - I had to move in closer because "Sun" and "Mercury" would be so entangled you couldn't read either.

I'm almost certain the Mercury dude at the Super Bowl is representing what you see in the screencap above in Capricorn.
