The Vengeance Formulation - S3-E9
Corrected entry: Kripke pumps helium into Sheldon's office to make his voice squeaky while conducting a phone interview. However, the helium is pumped in via a tube that is above the height of Sheldon's head, and helium floats in air; therefore, the helium would have accumulated near the ceiling and would not have affected Sheldon within a couple of minutes as shown.
Correction: Kripky opens 2 massive canisters of helium - enough to accumulate low enough to affect Sheldon's voice.
