Cleveland Cavaliers All-Star LeBron James had no mercy for New York Knicks big man Lou Amundson on Saturday.

Seeing that Amundson switched on to him, James aggressively drove and threw down a dunk right on the Knicks center's head. Immediately after dunking, James turned towards Amundson and taunted him with a staredown.

James received a technical for taunting Amundson yet he nor the Cavs (at least their Twitter account that is) didn't seem to care.
