Here's a challenge for you Hoss since you are so good at finding things....and I'm sure you will love it.
Johnny Carson used to make fun of British accents so somebody pulled a practical joke on him with hidden cameras. They planted a lady at a social event with a thick accent and she started a conversation with him. But her accent was so thick that it was not even something that anybody could understand....just gibberish disguised as a thick accent. It was so funny to see him embarrassed for not understanding it since he was often the one pulling practical jokes. I'd love to see it again if you can find it.
