"[[http://www.girlgeniusonline.com/comic.php?date=20070430 Yonder lies the castle of my father!]]", a quote from ''The Black Shield of Farnsworth'', which is generally considered one of the worst-delivered lines ever as the original actor had a very strong Bronx accent. usually rendered as "Yonda lies da castle of my fadda" to emphasise that Curtis was NotEvenBotheringWithTheAccent.

* [[http://www.girlgeniusonline.com/comic.php?date=20110228 If one looks closely]], it appears that [[Webcomic/TheAdventuresOfDrMcNinja Doctor McNinja]] has an office in the hospital at Mechanicsburg. Which... explains a lot.

* When Zeetha and Agatha [[http://www.girlgeniusonline.com/comic.php?date=20120425 check out armors]], some of them look [[TabletopGame/{{Warhammer 40000}} kind of]] [[{{Galactus}} familiar]]...
