(Penny opens the door to Sheldon and Leonard’s House. Leonard isn’t home.)
PENNY: Oh, hi Sheldon.
SHELDON: (pause). …Hello.
(Audience begins to giggle. They know something very funny is about to unfold.)
PENNY: Oh what are you doing, are you playing Xbox?
(Audience begins to laugh at a considerable volume. Some audience members have fallen off their seat in anticipation of the oncoming punchline.)
SHELDON No, Penny. This is an Xbox 360.
(Audience erupts with laughter. Multiple flares are lit up, and fireworks decorate the sky. Ambulances are called but do not arrive soon enough. The audience is laughing at such an outrageous volume that the studio begins to rumble. Amidst the cacophony of laughter, the ground splits open swallows the audience, and then the studio itself. None survive. The Big Bang Theory is declared to be the most hilarious TV show ever to grace earth. Many die in their homes when the episode goes to air.)
