Say what you will about Glee—as long as you say it’s “fantastic”—but unless you’re DEAD you have to agree that Jane Lynch’s “Sue Sylvester” is the funniest character on TV. And in anticipation of next week’s all-Madonna episode, Sue stars in this hilarious shot-for-shot remake of Madonna’s “Vogue.” Deeeeee-licious.
P.S. Why is Sue Sylvester doing Madonna sexier than Madonna doing Madonna?

I’ll admit (and not braggingly) to never having seen an episode of this show. Can someone give me a very brief synopsis? Is there a plot or just people singing? I skimmed the Wikipedia article but it had no real summary.
