This doesn't violate Newton's third law, because friction with the 
ground brings the Earth into the equation.

The situation you describe can easily arise, just because we are not of 
equal weights, and consequently have different levels of friction with 
the ground. This is, after all, why you can push a coffee cup away from 
you across a table without yourself getting moved backwards.
