For those of you with geese, try this one, which I guarantee does work:
Hold the goose still on the ground with one hand and with the other, place the goose's head under its wing. Then put your first hand over that wing to hold it in place.
Then, with your now free hand, repeatedly stroke very gently from the top of the goose's neck right down to its body. After a few times, you'll feel the goose start to relax, and you can take away the hand you've still got over the wing.
Keep stroking and you'll find the goose sort of goes to sleep. You can then get gentler and gentler with the strokes until you eventually stop and walk away quietly, leaving the goose asleep.
If you have a couple of geese (and people), you can turn it into a competition to see who can sleep their goose for longest
