Work Laugh

I've been at a conference in Atlanta for a couple of days now. I had to giggle at something today... I noticed that I have a work laugh. I saw a "Friends" episode once where Monica and Chandler had "work laughs," and I thought then "I wonder if I have one of those"... yep, it's true... it sounds a bit like this: aha, ha, ha, ha, haaaa (sigh)... in a up-tempo Guy Smiley sorta way. :) So, does this mean I'm fake...? Or just that I've acclimatized to the work environment? Hummmm :) Now I'm gonna have to play... name that "work laugh" at work.
