Two will always stand out for me, aside from the Yarema incident.
As an individual - Mike Rowe vs Nicky Chinn. Rowe, a legit tough guy, hit Chinny with a crosscheck by (if memory serves) Block 7 or 8 in the WNIR. Chinn, who's centre of gravity has always been in his skates, rocks back, leans, and comes back with an ungodly right that cleaned his clock and took Rowe out for some time. The best single punch I have ever seen in British Ice Hockey.
As a team? When Rocky called us a bunch of Homers....
