These resulted in the characters suffering from the consequences, such as embarrassment, humiliation, and all-around bad luck.

    In Season 1, episode 13, "The Bat Jar Conjecture," Sheldon assembles his own team to go up against the rest of the guys in the physics bowl. He employs his team with the intention to answer all the questions by himself but gets stumped at the last one. One of his teammates turns out to be a former physicist who gives the right answer, but Sheldon figures he would rather lose on his own than win with a team.

    After his defeat, he has to contend with the mocking Leonard throws his way - who flaunts his physics bowl trophy in Sheldon's face. Sheldon could have easily been the one to do the mocking had he simply decided to go with his teammate's answer.
