* The boss battle with Dracula replicates the prologue dialogue from ''VideoGame/CastlevaniaSymphonyOfTheNight'' word-for-word, with The Kid replacing Richter. And then... [[spoiler:he throws his wine glass at The Kid, killing him if he doesn't dodge it in time.]]
** And the ending of that battle.
--> [[VideoGame/CastlevaniaSymphonyOfTheNight BEHOLD]] [[{{Dracula}} MY]] [[OneWingedAngel TRUE FORM,]] [[LargeHam AND DESPAIR!!!]] [[spoiler:*[[ClippedWingAngel Turns into]] [[{{Kirby}} Waddle Doo]]*]]
* Also, "It's dangerous to go alone! Take this. [[spoiler:'''[[YetAnotherStupidDeath YOU JUMPED INTO A SWORD. YOU RETARD!]]''']]"
* The ending, which allows you to [[spoiler:[[KaizoTrap die at the end of the credits]]]].
* Ryu from StreetFighter coming out of absolutely nowhere and hurricane kicking the Kid into a pulp.
* The special death if Kraidgief gets hold of you: [[spoiler:[[FistOfTheNorthStar Hokuto Shinken]] [[StreetFighter Spinning Piledriver!]]]]
** Kraidgief. The sheer concept of Kraidgief is absolutely hilarious.
* The error box trap. Always funny to watch someone playing for the first time get hit with it.
* The funny music from Mario Paint that plays when you get hit by the airplane.
* "Die, monster!-! WHOZAWHAT? [[YouExclamation YOU]]?!"
** In the same cutscene:
-->The Guy: "[[WhamLine No. Not The Guy]]. [[spoiler: [[TheReveal THE]] [[LukeIAmYourFather FATHER]]!]]
-->The Kid: '''[[BigWhat "WHAT"]]'''
** [[spoiler:[[LukeIAmYourFather "Yes, I]] [[ParodiedTrope did have sex with your mother."]]]]
* Didn't escape the room with the Tetris pieces in time? A giant pill from Dr.Mario smashes you and it fills the whole width of the playing field to boot!
* In a certain level (before Kraidgief, IIRC), there are some spikes at the bottom of a room, but they cover only a small part of the floor. You'd think you could jump off safely... and if you try, the spikes get up on their legs and place themselves ''right below you''.
