Ran across this well-done and hell-of entertaining article from Environmental Graffiti about the history of Kangaroo boxing in Australia and other (less shitty) places. It's all one big highlight (as Kangaroo related things tend to be AWESOME) but the highestlight would be this kangaroo named Killer Willard boxing on a US television show in the 80s.
Killer Willard - U DA BES'!!!
Rap name: ILLER WILLARD?
