Ramona and Sheldon have lunch together at work, and they sure seem to be getting along well. The rest of the gang is worried about this (and so are we)!
Sheldon: I'll have a diet Coke. Penny: Can you please order a cocktail? I need to practice mixing drinks. Sheldon: Fine... I'll have a virgin Cuba Libre. Penny: That's... rum and Coke without the rum. Sheldon: Yes, and would you make it diet?
