* HardCore: [[http://roosterteeth.com/comics/strip.php?id=189 Parodied by a comic of Gus fervently swearing and threatening... while playing UNO on Xbox]].
* HarsherInHindsight:
** Any of the comics with the now deceased Creator/MontyOum.
** References to Geoff's drinking, now that he quit.
** Griffon and Geoff's relationship in general, now that they divorced.
* HilariousInHindsight: While the idea of a "hardcore" UNO comic seemed silly then, flash-forward several years to the release of ''LetsPlay/UnoTheMovie''. Watch grown men get increasingly irate over two and a half hours of Uno and that comic seems oddly prophetic.
