• The Fever opening night. Acorn Theater, 410 W. 42nd St., nr. Ninth Ave., 7 p.m. First staged in 1990, The Fever (written by and starring Wallace Shawn) involves an "anonymous narrator who wakes up in a war-torn country with a terrible fever, unable to reconcile the privilege he has enjoyed with his current surroundings." Hey replace, "country" with "living-room floor" and "fever" with "headache" and you've described our Saturday morning! Truly, this play speaks to the universal human condition.

P.S.: Parties will be sparse this week; the Super Bowl has sucked a lot of celebrity power to south Florida, while the rest of New York gears up for the Fashion Week kickoff Friday.
