One time, the Watchtower reader stumbled clumsily over the name of a French newspaper quoted in the Watchtower. He then, obviously without thinking, said: "Pardon my French." Big laughs....
On another occasion, the bookstudy reader was reading out of the Creator book ( or maybe the Evolution book....oh well ) and instead of reading "one celled organism " read " one celled orgasm." Much stifled laughter there...
Still another time, an Elders son, commenting on the wisdom of doing things Jehovahs way and waiting for the new system uttered a gem. He said,"Instead of getting involved in things like immorality and losing Jehovahs favor, we should wait for the new system, when we can have sex all the time." Needless to say, everyone got a kick out of that one, especially his father, who was conducting the part at the time.
