Why Does CalCentral Only Freeze, Not Slide to the Left or Crisscross?

After throwing my hands behind my head, I realized that CalCentral actually wasn’t threatening to arrest me, but was inviting me to do the Cha Cha Slide. Now I’m no AFX member, but I will admit that I’ve been to my fair share of Bar and Bat Mitzvahs. I patiently waited to be told to clap my hands and slide to the left, but to no avail — there was just silence.
