I also find it somewhat humorous. But rather than stand there and laugh I try to take more of a constructive approach by suavely walking over, straddling them by sitting firmly on there stomach in the direction of there head at which point I proceed to whap them on the forehead with my phallus while bee bopping the song 'eye of the tiger'. If you must know the whaps also emulate the beats of the song. After a couple minutes of this they are psyched and begging for more plates on the bar.
