Labs lab, thinking sky cat had hidden a couple of peanuts in her shirt, jumped (no mean feat for one so heavily endowed) up at
her, mouth agape. But being the astute dog trainer that she is, she deftly avoided its leap, and shouted "sit!" she even remembered the hand signal. Which it promptly did, then burped again, a haggis flew out this time, and run for the hills, leaving a trail of dog saliva in its wake.
Lab was amazed, he had never managed to train the dog to sit.
