One not mentioned on there though that brought a smile to my face was a reference during one of the SCH quests at Camp Bronze Lake, where you have to cast Leeches on invalids in the hot springs - one of the patients, a hyur woman suffering some kind of post traumatic stress, keeps chanting over and over "Can't sleep, mummer will eat me! Can't sleep, mummer will eat me!"

This is a humorous reference to a line Bart made as a toddler after Homer built him a scary looking clown bed during the season 4 episode of The Simpsons: Lisa's First Word ("Can't sleep, clown will eat me!" - a 'mummer' is an archaic term for a performer or clown).
