Oh, The Seventies. Is there any stupid thing you won't do, and still take yourself so seriously? No, there isn't. Here, we see The Seventies trying to sell us vodka because we want to be like those cool guys you see going a-falconing. Because you see that all the time.
Birds can sense nervousness, and Gordon's really takes the edge off. Don't be nervous around your falcon. Also, don't go falconing with any vodka but Gordon's, or he'll have his falcon tear your eyes out, and that's not the vodka talking.
