 After Frasier suggests that she change her hair style, Lilith does get a new hairdo - an afro - to which Frasier in particular cannot stop laughing. Lilith is hurt by Frasier s reaction. Ultimately, Frasier supports his wife, but needs a little help from Rebecca to do so. Meanwhile, it s Norm s birthday and among his gifts is a Boston Celtics jacket personally delivered by Kevin McHale. Before Kevin leaves the bar, he gets caught up in the typical trivia talk of Norm and Cliff, namely how many bolts there are in the Boston Garden basketball court. Carla warns Kevin of the obsessive power of bar trivia, but she s too late. Kevin is obsessed with knowing the number of bolts, which no one can tell him conclusively. He s up in the middle of the night wondering, but what s worse, his basketball skills plummet as he s busy counting the bolts rather than paying attention to the game. Sam, Norm, Cliff and Woody decide to go the Garden to count the bolts so that Kevin can get back on track. While there, Woody also wonders about the ice surface for the Bruins games, and he lifts up one of the basketball court floorboards. Just then, the guys are forced to take off immediately or else get caught by security. The next game, Kevin is playing well again as Sam told Kevin the number of bolts, albeit a made up number. Despite Kevin s prowess on the court, he faces a mishap when he steps on the floorboard Woody loosened, causing him to crash and leave the game with an ankle injury. That s when the guys confess to Kevin that they were responsible for his injury. Sam also confesses that he didn t know the number of bolts. Finally to get Kevin s life back on track, Kevin and Sam and Norm and Cliff and Woody count the bolts one by one.
