Grog's greeting "Ugh no gala ka kreeshta!" may be a reference to a similar phrase shouted at Will Smith in 'Men In Black' by the little coffee drinking monsters.
The shoots and leaves are a reference to the joke "A panda walks into a restaurant and orders a sandwich. When he has to pay his bill, he shoots the waiter. The panda gets up to leave, but the owner yells, "What are you doing? You shot my waiter and haven't paid the bill!". The panda replies, "I'm a panda! Look it up!" and promptly leaves. The owner went on the internet and found this: Panda Bears are known as an endangered species. They are recognized by their black and white fur. Eats, shoots and leaves.
