Or do the Carlton dance from Fresh Prince of Bel'Air!
As long as you can move to the beat, you're golden. Stand off to the side and tap your foot to the beat. If you can do that, step out, and rock your shoulders back and forth. Snap your arms... and keep time. it's pretty simple.
Oh, yeah, the bobbing your head rule only works if you can keep time to the beat.
Otherwise you'd look like you're having a spasm.
