Mick's solution to the problem of the kangaroo hunters; by the time he's through, the goons are scurrying home terrified that it seems that the kangaroos are shooting back!.
Mick's jovial non-reaction to a guy with a switchblade trying to mug him.
"That's not a knife. That's a knife."
In New York City, two women approach Mick to do him a... favor for free. The man they're with threatens Mick, but Mick, being Mick, punches him out in one punch. Later, he comes back... but he's outnumbered three to one, and Mick, despite putting up a good fight, is defeated. Then, the man who was driving him around arrives and runs into two of them and throws something at the fleeing third assailant, knocking him out.
And the thing he throws? It's the boomerang-shaped ornament from the top of the pylon on the trunk lid.
