Listen, I give them this: the roommate deal is fun and was a reliable source of comedy, but is it legally valid? The issue was indeed raised in the show; In season 4, Leonard was with Priya Koothrapali, a lawyer and sister of his friend Raj. When Leonard`s relationship with Priya came into conflict with Sheldon`s claims, Priya argued to Sheldon that the agreement was unenforceable. What for? Sheldon took his love of rules and guidelines to the extreme and created an epic roommate deal that Leonard must accept to live in. Although Leonard wasn`t always able to stick to the deal, he tried to save face in front of Sheldon so as not to upset him. Nevertheless, these are just 10 of the rules of Sheldon and Leonard`s roommate deal, which brought all that laughter into the longtime show. According to the roommate agreement, Sheldon insists on having different types of food different nights of the week. Especially Thursday was pizza night – pizza jets, nothing less. If Sheldon or Leonard wanted to change it and try something new, they would have to have a public hearing with a “60-day comment period.” If two roommates have a roommate agreement, I could see that the majority of the rules are surrounded around the bathroom. . . .
