Speech can only listen to one side--Joke

A judge asked our group of potential jurors whether anyone should be excused, and one man raised his hand. 　　
I cant hear out of my left ear, the man told the judge. 　　
Can you hear out of your right ear? the judge asked. The man nodded his head. 　　
Youll be allowed to serve on the jury, the judge declared. We only listen to one side of the case at a time.
