* The letters Willie give you.
** Most notably the one that goes; "If you throw this away I will think less of you."
* "Sound Effects Record #32":
** Man Watching Television with Volume at 0: Total silence
** A Mime, [[TakeThat and His Audience]]: Total silence
** Dead Insect: Total silence
** A ''Swarm'' of Dead Insects: [[OverlyLongGag Total silence]]
* Klaymen running away from the [[CallASmeerpARabbit weasel]]. He runs up to the door, opens it and [[RuleOfFunny runs straight into the wall]].
** He then sees the weasel, ScreamsLikeALittleGirl, ''shuts'' the door and [[EpicFail runs into it]].
** Willie eating the Weasel's now-cooked remains after you FeedItABomb. Watch [[https://www.youtube.com/watch?v=qIsgRgmT9MA&t=2m17s here]].
* [[OverlyLongGag The ballberry bush]].
* The ending theme song has a subtle gag where the singer accidentally comes in too early.
* The 'Beans' cutscene in ''Skullmonkeys''. Klaymen finds a can of beans and starts eating, as a evil-looking skullmonkey is creeping up. Klay finishes, farts through his ''[[BizarreAlienBiology antenna]]'', and flees when he sees the monkey...whose head melts from the methane. Bonus points for the "Beans, Beans, The Musical Fruit" song that plays when Klaymen's eating the beans.
* The [[spoiler:"Klogg is dead"]] song (Watch it [[https://www.youtube.com/watch?v=4BUmv8imdH0 here]], but beware spoilers!) from ''Skullmonkeys''.
