Is anyone else alarmed that a kangaroo apparently knows what a headlock is? [Careful with the audio, it's a little loud.] From Laughing Squid:
During a last wish boar hunting trip for a boy with terminal cancer, the group discovered that a big buck kangaroo had Greig Tonkins’ beloved dog in a deadly headlock. The 6’7″ Taronga Western Plains Zoo employee made his way towards the animals, causing the giant marsupial to become distracted and let go off the dog. For a few moments neither man nor beast showed any sign of backing down. In an effort to break the standoff, Tonkins punched the kangaroo across the snout and took off the other way. The roo was stunned by the blow and hopped away confused, but unharmed.
