With the perennial winning team not participating this year, Leonard, Howard and Raj feel that their foursome are the sure winners of this year's edition of the university's physics bowl. They have to talk a reluctant Sheldon into entering with them, which they do manage to do. They regret doing so after Sheldon takes control of everything and as such has taken any fun out of the process. After the threesome kick Sheldon off their team, Sheldon vows revenge by forming his own team. Despite Leonard's discomfort with the idea, they decide to ask Leslie Winkle to be Sheldon's replacement, she who declines until she learns that they are planning on destroying Sheldon in the process. During their match, Sheldon, who believes he is basically fielding a one man team (his teammates are a janitor, the lunch floor monitor and her son), has to decide what is the most important goal.

Did You Know?


Leonard (Johnny Galecki) (and P.M.S.) won a trophy for a non-championship match. When Dr. Gablehauser first introduces the teams, he stated that it was "today's preliminary match." Unless there were only a few teams in the tournament, it is unlikely that they would get a trophy for an early-round victory. See more »


At the end we watch how Leonard sits in the spot of Sheldon and he doesn't say anything, also he sits in another spot without complaint, this kind of behavior differs of the usual Sheldon behavior about sitting in his spot or that someone sits in his spot. See more »

In the opening scroll of the time line when it gets to 91,000 there is a mistake the dates read 93,000BC 92,000BC 91,0009C 90,000BC for some reason 91,000 is a 9c not a BC. See more »
