Sheldon and Howard in “The Monopolar Expedition”

[Leonard, Raj and Howard are in the Cheesecake Factory freezer along with Sheldon, forced by the latter to perform exercises that mimic the movement of their tasks when they will be at the North Pole, but after less than a minute they have enough]

Sheldon

Gentlemen, use your imagination. Innovate. Did Han Solo let Luke Skywalker freeze to death on the ice planet of Hoth? No. He cut open a tauntaun and used its internal body heat to warm him up.

Howard

You heard the man. Hold him down and I’ll cut him open.
