Zimmerman trial starts with F-Bombs and knock-knock joke

An F-bomb and a joke that bombed. That was the shocking start to George Zimmerman's Trial.

Both sides laid out their opening arguments to a jury of six women. The racially charged trial coming 16 months after Zimmerman shot and killed teenager Trayvon Martin.

It became clear the moment the prosecution and defense went head to head - that they both had very different and distinct approaches when it came to driving home their point.
