Holy god can we please not do the wave at a hockey game? It's not football. There is no third quarter. There aren't forty seconds between plays. It's a continuous game and there's no reason to ignore what's happening on the ice to do this damn wave.
Furthermore, the idiots who started the wave sent it backwards. Seriously, don't do it.
I will continue to scream at you to stop the wave until my voice cracks and blood gushes from my throat.
Please cease this terrible action.
