The entire game is pretty much this. See below for particularly funny parts:

* "Y'know what's really stupid? Driving a car around in a populated office building. That's what's really stupid."
** Most of level 3 in general, really.
* [[LampshadeHanging "How many fathers do you have?!" and "Watch out for your dear old mother! She's literally everywhere at once!"]], written on [[DeadpanSnarker signposts]] next to areas with multiple instances of Clarence's father or mother.
