Walking: Intersubjectivity

So this exercise I was kinda excited about because its fun to mess with people... and this time I had an excuse...
But unfortunately my dreams of freaking my friends and coworkers was halted by the realization that most of the things I thought of doing, which I wont go into, would probably end badly for me in my work environment. So I decided to do something more modest...
I fake laughed and not just at funny things but also awkward moments like when Doctor Hibbert from the Simpsons would laugh (where I drew my inspiration).
First I should mention that I laugh a lot and I've also been told on many occasions that I have a great and infectious laugh. I wasn't counting on it but my coworkers caught on within an hour and called me out on it. They knew there was something up so I caved but didn't give up because I wanted to see how strangers would react that weren't accustomed to my laughter...
I had a mixed reaction because of my choice moments that I would laugh and my kind of laughter. It made me wonder though, sometimes, if thats how people actually react a strangers laughter, because I was paying so much attention, or was it because my choice of laughter was strange...
Well I can say for my own experience that theres definitely some people who just laugh funny and when you first hear them laugh you kinda stop for a second to make sure that that laughter is as odd as you think. Theres also the forced laughter thats usually a kind of "kiss ass" laughter that can sometimes just, of course I'll never know, be a funny laugh. I work in retail as a sales man and I definitely got some looks that felt like the person thought I was giving them the "kiss ass" treatment. Either way my coworkers were entertained...
At home later in the evening my girlfriend didn't even hesitate she knew I was being weird and she called me out in less than 10 minutes... As much as I like messing with people I have a hard time keeping a straight face... yeah I suck at poker...
