How do you attract a flock of emus? This wildlife guide shows a great trick: lie on your back and pump your legs like you're riding a bicycle upside down. Do it and they will come.
An interesting moment comes at 1:15. The man sits down and the emus promptly scatter. But once he resumes the bicycling movement, they come back.
Try it! Go outside somewhere, like a shopping mall or a public library, flip on your back and begin cycling. Emus will eventually show up.
