I have decided to pilfer this image of Bush,jr from Jonathan Schwarz, so I might engage in some shallow commentary, as follows:

what does this gesture mean? I have seen jr do this numerous times. To me it looks like he's trying to grasp a very large barrel. presumably this barrel is invisible, and only he can see it. also, he tenses up his shoulders whenever he attempts to open or grasp this magical, invisible barrel. maybe he's afraid that there might be a family of angry lemurs inside said barrel. or something else...
