[Discussing a large box of furniture which they have to take to the fourth floor, with the elevator out of order]
Leonard: Well, we'll just have to take it up ourselves.
Sheldon: I hardly think so.
Leonard: Why not?
Sheldon: Well, we don't have a dolly, or lifting belts, or any measurable upper body strength.
Leonard: We don't need strength, we're physicists. We are the intellectual descendants of Archimedes. Give me a lever and a fulcrum and I could lift the earth.
[The package starts falling on him]
Leonard: I don't have this! I don't have this! I DON'T HAVE THIS!
[Sheldon lifts the package off him]
Sheldon: Archimedes would be so proud.
Leonard: Well, do you have any ideas?
Sheldon: Yeah, but they all involve a Green Lantern and a power ring.
