In game 4 of the NBA finals, Dirk Nowitzki led his Dallas Mavericks team to victory over the Miami Heat, despite suffering from a 101-degree fever and looking visibly sick at times.

It was the kind of performance that sports writers love to wax poetic about. But that didn't impress Heat superstars Dwyane Wade and LeBron James. In fact, right before game 5, a camera caught the duo making fun of Nowitzki's illness by fake coughing and sneezing.

Of course, Wade and James weren't laughing at the end of the night, when a healthier Nowitzki helped the Mavericks to another win - not to mention a 3-2 lead in the series. Check out the mockery below.
