By dance do you mean Fight/Punching? It wasn't really a fight, Ribeiro just lost his cool and punched Turris a couple times and got a roughing penalty. Cost his team. Smartly Turris didn't retaliate. So I guess you could say "Thanks for the Playoff Spot Ribs".
Turris and Ribeiro had a hold of each others jerseys. There was some pushing and shoving going on. Ribeiro starts gives Turris some little jabs. They give Ribeiro a penalty because it was completely unnecessary and the Caps had been starting scrums after every whistle.
The Caps were being really chippy and a bit dirty (slewfoot). I think the guys got the message to focus on the game after the Cooke debacle because they were pretty smart about not evening up those penalties after the whistle.
