* CuteButCacophronic: Halley, Howard and Bernadette's baby, spends much of her time crying.

* AgonyOfTheFeet: In "The Geology Elevation", Sheldon hurts his foot with a rock when it drops while he was trying to throw it. He then hurts his ''other'' foot kicking said rock in frustration.
* AmusingInjuries: Sheldon goes through a series of them throughout "The Geology Elevation". First he drops a rock on his foot while trying to throw it, then hurts his other foot kicking it. Then he slips and hits his head on a water fountain while he was trying to punch it. And finally, he hurts his hand punching (or rather, karate chopping a la Captain Kirk) [[spoiler:Burt for saying that he could do better than Amy.]]

* CatapultNightmare: Sheldon in "The Veracity Elasticity", when he dreams that Leonard and Penny turned his old bedroom into a sex dungeon.

* DumpThemAll: Inverted in "The Hot Tub Contamination". [[spoiler:In conversation with Stuart, Raj claims he's back to being single and not by his own choice, implying that both Emily and Claire have ditched him. Which would explain why neither of them had been seen since the end of the previous season.]]

* YourApprovalFillsMeWithShame: Howard shops around a Creator/StephenHawking remote control toy to see if others consider it offensive. Bernadette, Amy and Leonard all think it is, but it's Barry Kripke thinking it's hilarious that convinces Howard that it is offensive.

* PrimalScene: In "The Hot Tub Contamination," Sheldon confesses to Penny that he once saw his father making love [[spoiler:to a woman other than his mom]] and he never spoke to him again.

* CerebusRetcon: Throughout the years, Sheldon's habit of knocking three times was funny. As of "The Hot Tub Contamination," we now know why he does this: so that people can get dressed in time before he enters a room.
