This Slip-Up occurs when Laurie/Keri and Will are at her place. This is after she tells him that Michael Myers is her brother. Keri gets a bottle of vodka out of the freezer and unscrews the bottle to take a drink. She hands the bottle to Will and he unscrews it again to take a drink. The bottle has been unscrewed twice in the matter of seconds. Not a big slip-up if you don't catch it, but it's pretty funny when you see it.
