12 Times Sheldon Cooper Was Actually Wrong

List RulesVote up the most satisfying moments when Sheldon Cooper got out-nerded.

The idea that Sheldon Cooper of The Big Bang Theory can be wrong usually isn't broached in the series, as he's established as the smartest character among the cast. However, he's been wrong more than several times due to a combination of his arrogance, lack of pop-culture knowledge, and tendency to overlook small details that ultimately result in his entire project going up in flames. Still, these moments carry with them quite a lot of comedy, so it's worth checking them out.

    In Season 4, episode 2, "The Cruciferous Vegetable Amplification," Sheldon tries to adopt a healthier lifestyle, but at nighttime approaches Leonard in great pain, claiming he's about to perish. Leonard starts off by telling him he must have had something odd to eat as Sheldon has been changing his eating habits.

    However, Sheldon is adamant that it's serious, leading Leonard to think Sheldon may have appendicitis. Sheldon takes a more bleak, drastic outlook by screaming in agony that his appendix is about to burst. A few moments later, it turns out he had gas all along from the Brussels sprouts he had eaten, meaning his belief he was dying was far from correct.
