Every once in a while, Saturday Night Live shocks me by being right on my dance-nerd wavelength. (Have you seen the classic sketch "Bad Ballet"? You should.) Last Saturday, the totally bizarro—and yet spot-on—"Liza Minnelli Tries to Turn Off a Lamp" skit had me on the floor. Not only does Kristen Wiig nail it as a whackadoo Liza, but her moves aren't half bad. And there are a bunch of legitimate dance references in there! A few choice samples:

"There's gotta be like a ball on the end of a chain, remember that? Chain, ball, kick, chain!"

"Will a Fosse neck do it?"

"Look how long this cord is—Ben Vereen, it's long!"

"I'm not getting anywhere with it—it's like Tommy Tune!"

Also, her dance-off at the end with Jonah Hill is priceless. Check it out:
