Corrected entry: While the group are trying to figure out how to play Halo without Howard, Leonard jokingly suggests cutting Raj in half. Raj responds, "Oh sure, cut the foreigner in half. There's a billion more where he came from." But Penny is in the room with them, so there's no way he should be able to talk in front of her, or even if he's been drinking, the fact alcohol helps him isn't realised until the next episode, so the fact he can speak with her there should have surprised everyone, including him.
Corrected entry: When Penny tells Sheldon that he forgot a plasma grenade, she presses the right trigger on the Xbox controller. On Halo 3, the right trigger fires weapons, not grenades. That's the left trigger.
Correction: In Halo 3 you can change around some features of the remote, including which trigger fires grenades and weapons.
Corrected entry: Sheldon states that reductio ad absurdum is "the logical fallacy of extending an argument to a ridiculous extreme and then challenging it". This is incorrect; this is the straw man fallacy. Reductio ad absurdum is the entirely valid inferential technique of demonstrating that the consequences of an argument being true result in a contradiction.
Correction: Sheldon is correct. "Reductio ad absurdum" (Latin: "reduction to the absurd") is a form of argument in which a proposition is disproven by following its implications logically to an absurd consequence. Proof by contradiction is a specific form of Reductio ad absurdum. http://en.wikipedia.org/wiki/Reductio_ad_absurdum A strawman argument is committed when a person simply ignores a person's actual position and substitutes a distorted, exaggerated or misrepresented version of that position. http://www.nizkor.org/features/fallacies/straw-man.html The major difference between the two is that an Reductio ad absurdum argument presents the opponent's claim correctly but carries it to an extreme. The Strawman argument presents the opponent's claim incorrectly.
Corrected entry: Characters in Halo games can never be decapitated, as Penny states about Sheldon's player character.
Correction: Penny is on the other side of the room and not in the conversation. Raj's comment was an aside to Howard and it can be reasonably concluded that nobody else could hear.
