I always wanted to have a real, true and very noticeable accent. I love them. I still toss in an accent here and there just to make my stories sound better. Several years ago I got bored at a case staffing at the agency where I worked so I did my entire case staffing with a Russian accent. I was pretty new to the group and several people thought I might be Russian. I loved that.
Speaking of accents, I found this clip with Robin Williams doing a short series of different accents on Ellen's show. Evidently Robin was challenged to do these accents to raise money for Comic Relief and, as usual, Robin was up to the task of performing.
I hope you enjoy this (btw I wrote that with a Turkish accent to honor my friend, Derya).
