Yes it is true! John Denver being kicked out of the Johnny Carson show.
I clearly remember the night I saw that episode. It was the same night that a smurf starting walking out of the Kingdom Hall and cussing.
On his way out of the Kingdom Hall, a pioneer sister tried to stop the smurf to place a magazine and count her time. When he flipped her off, the pioneer sister said she wasn't afraid as she was the same person that knocked on the door of a serial killer and he didn't harm her because she had 2 angels protecting her. Since this smurf was causing a disruption of the meeting, an elder approached the talking, walking smurf leaving the kingdom hall and offered him a bible study. This elder told the smurf that JW's have the truth because the gameshow Jeopardy had a question about who is the smartest man on earth an the answer was Fred Franz. The same elder also told him about another episode of jeopardy where the question was what is the best bible translation on earth? And the answer was of course the New World Translation. Upon seeing that the smurf didn't want to stay for the rest of the meeting, the elder made an announcement that the smurf is no longer allowed to enter the KH for being mentally diseased and anyone seeing those cartoons will be df.
Everyone lived happily ever after except the smurf of course for rejecting the truth.
