I went to high school with some guy who was major flake and a compulsive liar. I never got to know him well, but he was always doing things to get attention like wearing dresses and trying to sue the school. A couple of years later I went with a friend to visit his girlfriend at a university in another city. She wanted to introduce us to her new friend, a most interesting guy from England; the nephew of a duke or something. It turned out to be that dork from high school speaking with the worst fake accent imaginable. When he recognized me he turned red and quickly beat a hasty retreat.
It sounds like the guy in the movie "There is Something About Mary" who pretended he was English and a cripple.
I knew a guy in college who was also desparate for attention. He used to change accents several times during a conversation and claim he didn't know he'd done it. He said his family moved from country to country when he was young, and the accents were ingrained in him. The change over was completely involuntary. YEAH.....RIGHT! I always did feel a bit sorry for him though. It's sad to see anyone so desparate that they feel the need to make a joke out of themselves.
What is it with these people?
