I call this one "glasses dude in the headset with the laptop holding a sheet of paper and a nice beverage." Clearly he's very happy about something. The question is, what? Perhaps someone just told him a joke on his headset or maybe he's in the process of reading something funny on his computer. These are definite possibilities but they're certainly not the only ones. It could be that he just took a sip of his beverage and it was delightfully refreshing, however, it also could be that his smirk is the result of the giddy anticipation he feels as he prepares to take a sip. Or perhaps someone who is in the room but not visible in the photo has made a funny little face that has brought on the laughter. Then there is the paper possibility. Though he is not looking directly at the paper, it is entirely plausible that he has just seen something quite amusing written on it and is only momentarily glancing away. Or could it be that the cell phone on the table rang at that exact moment and he is overjoyed that someone is actually trying to reach him? I wouldn't rule that one out. Nor can I rule out the possibility that he has just recalled something that happened earlier that day and that this alone has produced his expression of joy. And lastly, there is the remote chance that he is not really reacting to anything at all, but rather, walks around with that stupid grin on his face all the damn time. I guess there's no way of telling for sure. Alas, the truth is, we will probably never really know the secret behind the smile.
