In the past Australia and the Lions have had quite fiery encounters, with big punches as prevalent as big tackles or breaks. Thankfully someone put together a montage of the best fights. Come for 1989 player of the series Mike Teague haymakering his opposite number, stay for Graham Henry's great post match interview in 2001.

Waratahs coach Bob Dwyer has a point about Henry: he has a very Arsene Wenger-esque approach to what incidents he sees. Having said that, Dwyer is talking out of his ass, as most Australian rugby people tend to do.
