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.
