* Too many to mention without it becoming tedious, but they include the lesbian shotgun wedding and Creator/MontyPython special encounters in ''Fallout 2'', the Garys in Vault 108 in ''Fallout 3'', and loads more.
** Likewise, ''Fallout: New Vegas'' features the trait "Wild Wasteland", which adds several things to the game similar to the special encounters from the first two games, such as [[Film/IndianaJonesAndTheKingdomOfTheCrystalSkull a fridge containing a skeleton]] [[TakeThat wearing a fedora]], the late [[Series/CSIMiami Investigator Crusoe]] (or [[ThePinkPanther Clouseau]] in some versions), and a fight with [[Creator/MontyPython Hell's Grannies]].
* Probably [[ToiletHumor immature]], but there are quite some laughs at exploiting the Tell-Me-Abouts in ''Fallout 1'' and the characters' limited responses if they don't recognize the line of text you entered.
-->''types: What's that lump in your pants?''
-->'''Morpheus''': That's nothing. You may ask something else.
-->''types: Do you have a small penis?''
-->'''Morpheus''': That's not important.
-->''types: Did somebody fart in here?''
-->'''Morpheus''': Nothing to be concerned with.
* MANY of the conversations in ''VideoGame/{{Fallout 1}}'' & ''[[VideoGame/{{Fallout2}} 2]]'' when playing a "stupid" (Int < 4) character. For example:
-->''Drug dealer starts a lengthy sales pitch to player''\\
'''Chosen One''': Okay. Me have to go n-\\
''Drug dealer continues talking''\\
'''Chosen One''': ME HAVE TO GO N-\\
''Drug dealer continues talking''\\
'''Chosen One''': ME GO LET ME GO LET ME GO\\
''Drug dealer finally finishes their pitch and asks what the Chosen One thinks''\\
'''Chosen One''': Me forget! Me finally had a thought and you make me forget! ME KILL YOU!
* [[BlackComedy If you have a dark sense of humour]], some of [[BloodyHilarious death animations]] are outright hilarious, especially with the Bloody Mess trait/perk. Special mention goes to [[MegatonPunch punching a hole]] ''through'' someone.
* Shooting Marcus (the friendly Super Mutant) in the groin will not only cause him to yell "Oof!" and slump to the floor in agony, but leave him lingering there for several days. Shooting a woman in the groin will elicit comments like "Character's childbearing operations have been compromised" and "She takes it like a man. That is to say, it hurts like a motherfucker."
