(the guys are all wearing the same Flash costume)
Sheldon: This is why I wanted to have a costume meeting!
Leonard: We all have other costumes. We can change.
Raj: Or we can walk behind each other all night; it'll look like one person going really fast!
Howard: No, this is a boy girl party, this Flash runs solo!
Leonard: How about this: nobody gets to be the Flash; we all change. Agreed?
Raj, Howard, Sheldon: Agreed.
Leonard: I call Frodo!
Raj, Howard, Sheldon: DAMN!
