Some I remember.
One lovely brother, now dead reflecting about the eee=light (elite) he had read about in the WT.
Reading organism as orgasm.
I heard a recording of a convention talk where the bro used octopus features in an illustration. He repeatedly said "testicles" instead of "tentacles". After a few examples you could hear the penny drop. He had to decide whether he should continue his mistake or change to the correct word and admit his blunder.
I think I would have just said "aww bollocks" and moved on.
