Leonard: Hey, Sheldon. We found something pretty interesting.
Amy: Huh. Well, that is surprising. I, for one, have no idea what they're talking about.
Leonard: Turns out, when Amy took over Penny's apartment, she was put on the lease, not you.
Penny: Yeah, and when I moved across the hall, you got taken off the lease and I got added.
Amy: Well, what are you saying? That Sheldon's not technically a tenant at all and therefore, has no standing to be president of the tenants association no matter who votes for him? I don't know how you found that out, but I am guessing all on your own.
