Given Sigourney Weaver's most famous movie line Aliens' ''Get away from her, you bitch!'' it's odd, even off-putting, to watch her take on the mannerisms of a large, WASPy bunny rabbit to play A.R. Gurney's Mrs. Marjorie Farnsworth, a desperate Connecticut housewife attempting to write a memoir about how she may or may not have been impregnated by George W. Bush during her college years at Vassar. Weaver eventually settles into her role, but the play fleetingly fun never really does. The humor in Mrs. Farnsworth tends toward the heavy-handed (Hey, Bush is dumb! Ha!), and carries an obvious expiration date: Election Day 2004.
