In today's cringe-worthy news, Donald West, the defense attorney for George Zimmerman, opened his trial proceedings yeterday by telling an incredibly unfunny knock-knock joke. Although the joke was intended to illustrate the difficulty of selecting an unbiased jury in such highly publicized trial, it has drawn a lot of criticisms online and in the news media for being in bad taste, including American lawyer Alan Dershowitz who told CNN that Zimmerman might want to request a mistrial due to his lawyer's inappropriate remarks.
