With only two months to complete the contract for the Air Force, Howard, Leonard and Sheldon are working around the clock. Sheldon in particular is feeling sleep deprived as someone who doesn't drink coffee to stay awake. Feeling delirious, Sheldon, during one of the guys' working sessions, is lured to the dark side by the hallucination of one of his idols, the dark side being an energy drink.

We do not add artificial or "canned" laughs. If something isn't funny our job is to make it funny, not pretend it is.
