So there's some sort of fun musical number going on and one character, usually a villain, is not joining in on the fun. They're either watching with a scowl, or have something much more important on their mind. The character looks over to his lackey or partner, only to see them dancing along! Often followed by a sharp glare and the lackey sheepishly stopping.

- Occurs in Rocky Horror Picture Show when Rocky, as well as all the nameless Transylvanians and Columbia, start dancing along to Eddie singing Hot Patootie much to Frank's dismay/jealousy.
