ESPN2's cameras captured the midfielder making a funny face while running his mouth at an opposing Jamaican player.
During the World Cup qualifying group game in Columbus, Dempsey had some words - and a funny face - for the Reggae Boyz's Ryan Johnson that was shown on the ESPN2 telecast.
This isn't the first time Dempsey has had a temper on the pitch.
Last season, while playing for Fulham, the 29-year-old literally went head-to-head with Liverpool's Craig Bellamy. In the past, he has broken John Terry's jaw and given Phil Jones a concussion.
Dempsey was unable to find the net against Jamaica on Tuesday after scoring the U.S. team's only goal in a loss to the Caribbean nation five days earlier. It was the second straight game he went a full 90 after missing the preseason while with Fulham before completing a transfer to Tottenham two weeks ago.
Dempsey looked tired on the pitch but his mouth always keeps going.
