A man is arrested in Oklahoma. He has a choice between two Public Defenders. One is brilliant at picking a jury, though his trial tactics are somewhat suspect. The other is superb on his feet but not so adept at picking a jury. The accused opts for the former.
The trial commences. The jury is selected and the prosecutor opens his case. "Ladies and gentlemen of the jury, this is a simple case. You will hear sworn evidence from the accused's next-door-neighbor who will tell you that he made the following observations on the day in question. Early in the morning he observed the accused emerge from his back door and enter his yard. In the yard there was a pump to which was tethered a goat. The accused approached the goat from behind and dropped his trousers. He then commenced to have sexual relations with the goat. He continued for about 3 minutes then withdrew. The goat then turned around and licked the accused's genitals."
At this point the Okie knew he had picked the right lawyer when juror number 1 turned to no. 2 and said, "A good goat'll do that."
