Tampa Bay Lightning goalie Ben Bishop went to stop a routine dump in from Joakim Andersson when things went all sorts of wrong. The puck deflected up and when he tried to clear it away, he accidentally knocked it backwards with his stick. The puck went off the crossbar and then bounced/rolled slowly into the net. Truly an unfortunate bounce for Bishop and the Lightning.
