Is there an offensive and a non-offensive way to press one's hand against a wall? In the first picture, emotional Witchita State basketball coach Gregg Marshall surrounds petite sideline reporter Tracy Wolfson. If he wasn't disappointed after the loss, I would think that's he's hitting on Tracy at a bar, and needs his hand on the wall for support, as he's inebriated. Tracy is so understanding, patient, and kind, playing into feminine stereotypes -- the passive feeler to the active man.
In contrast, comedian Louis CK has made putting his hand up against a way part of his comedy routine, at least when he plays small clubs. (Stages do not have walls.) Louis awkwardly presses up against the wall, silently supporting himself against needs of the audience, and prepares to sheepishly observe on the darker elements in all our lives. (CK has been criticized for using the topic of child abuse as comedic fodder.)
In sum, Louis CK is the best man-pressing-hand-against-wall, but neither can hold a candle to Ulysses S. Grant.
