Leonard: Sheldon, I told you, I only have access to the free-electron laser at night. I can't drive you for the next few weeks.
Sheldon: No, you said you couldn't drive me to work, this is from work.
Leonard: Howard, help me out here.
Howard: No, just for the fun of it, I'm gonna take his side.
Sheldon: Now, how do you propose I get home?
Leonard: How did you get here in the first place?
Sheldon: Penny. But I sense that's no longer an option.
Leonard: Look, I need to get to the laser lab, you're just going to have to find someone else to take you home. [Sheldon looks to Howard]
Howard: Oh damn, I picked the wrong side.
