The Codpiece Topology

Penny is dating a new guy, so Leonard jumps at the chance to date Leslie Winkle again. Sheldon hates Leslie and resents being exiled to the staircase to play Mario alone. Eventually he confronts Leslie about her scientific beliefs and when Leonard doesn’t agree with her she leaves.

Quotes

 * Sheldon: Everybody has a date. Even you Mario going after Princess Peach. And what am I doing? I'm just enabling you.
 * Raj: What happens in costume at Comicon stays at Comicon...

Trivia

 * Sheldon won't go to the movies alone, since no one would be readily available to give him the Heimlich maneuver should he choke on his popcorn.
 * Sheldon doesn't drink coffee (nor eats Bear Claws), so finds no lure in coffee shops.
 * Sheldon doesn't like dining alone, because if he has to go to the restroom, there's no one to ensure that no one is touching his food while he's away (which is a grievous offense, and earns one strike with Sheldon)
 * Apparently the multiple attempts to get Penny to understand Schrödinger's Cat in The Tangerine Factor did stick at least somewhat; she's overheard trying to explain the concept to her new date in this episode.
 * Several comic book supervillians apparently have doctorates degrees, as Sheldon suddenly realizes after naming Dr. Doom, Dr. Octopus, and Dr. Sivana.
 * The deal breaker for Leslie is that Leonard believes String Theory better unites Quantum Mechanics with General Relativity than Loop Quantum Gravity, and she doesn't, and with the two of them on different sides of the fence on this issue, which theory will they raise their children to believe in?
 * The title comes from the quote Sheldon says about the Renaissance Fair being inaccurate to the time period and says it is only held as an excuse to wear a codpiece.

Censored

Tonight's vanity card is about censorship. It was censored. As always, you know where to look.

Critics
"The Big Bang Theory has good comedy writers. This episode sparkles with fun one-liners, insults and gags. But those writers need to focus on stories and characters which will hook a loyal audience. Sheldon dominating every scene will eventually become tiresome and the wealth needs to be shared around the group. But for now this is a fun episode." - The TV Critic's Review
