* AcceptableTargets: Elvis impersonators. Whenever they appear, killing all of them will give you a bonus, as well as the announcer [[LargeHam bellowing]] "'''[[IncrediblyLamePun Elvis has left the building!]]'''"
* AntiClimaxBoss: All of the bosses, once the player has completed all of the missions. They come without reinforcements despite not being especially strong in any way - thus, the final mission of each level is just to kill three random enemies as they come.
* EarWorm: [[http://www.youtube.com/watch?v=qbIFx1u8jzc Taxi Drivers must DIE!]]

* WhatAnIdiot: Incredible stupidity among non-playable characters is incredibly rampant, whether by design or by programming limitations or [[ThrowItIn both]].
