Sheldon: Lois Lane is falling, accelerating at an initial rate of 32 feet per second per second. Superman swoops down to save her by reaching out two arms of steel. Miss Lane, who is now traveling at approximately 120 miles an hour, hits them and is immediately sliced into three equal pieces.
Leonard: Unless Superman matches her speed and decelerates.
Sheldon: In what space, sir, in what space? She's two feet above the ground. Frankly, if he really loved her, he'd let her hit the pavement. It'd be a more merciful death.
"You know, Spider-Man and Superman make it look so damn easy. Why doesn’t the person falling three hundred feet get a broken neck, or at least a whole stack of cracked ribs, when Spidey snags her with a web?"
