Penny could have told Jimmie Fallon how to eat vegemite on toast, without seeing Hugh Jackman do so.
She, like any true-blue Aussie dog, loves her toast with vegemite. (Or peanut butter, for that matter.)
Even if her humans are miserly with the bread. (Bread isn't really good for her.) That's her teensy piece on the edge of the plate.
But she's willing to go through her routine of tricks to see which one will be randomly rewarded on this occasion. She usually does a couple of spins, one direction after another, to see whether that earns a response, then backs away, tries a short 'speak', takes a bow, or gets up on her hind legs (wonderful to see she can do this now, after her cruciate surgery five years ago).
Today, it was the hind legs raise that got the tiny reward.
