* KHAAAAAAAAAAAN!
** To explain this, in ''Legacy of Time'', you go to Shangri-La. There, you meet Ghengis Khan. When you walk the underground passages of the temple, you can climb up just behind him. If you do, he turns around and punches you back down the ladder. Arthur will then appropriately speak the immortal line.
* [[https://www.youtube.com/watch?v=2ujtbfCE92Y&feature=related Here]], skip to about 3:40. Also, pretty much anything Arthur says.
* ''(when trying to approach a person with their own Chameleon guise)'': "Can you ''imagine'' how that person would react if an exact mirror image walked up and said 'Hi!'[[CallBack ...Well...I guess]] ''[[CallBack you]]'' [[CallBack can.]]"
* "Maybe we can put this guard to sleep! [[TakeThat Quick, Gage, go talk to him about your love life!]]"
* That NonStandardGameOver in ''Buried In Time'', where two castle guards literally [[DropTheCow drop a cow]] on you if you take too long climbing the tower to the keep of Chateau Gauillard. The best part? The whole scene is a ShoutOut to ''Film/MontyPythonAndTheHolyGrail.'' Arthur even quotes the famous "Elderberries" line a little ways back while on the castle parapet.
* A couple of the empty apartments in the first game have some funny messages on the intercom buttons left by their owners.
--> "I'm on vacation I won't be back for--" [[MadLibsDialogue 2 WEEKS, 5 DAYS, 6 HOURS"]] "Thank you."
--> "''Come iiiin!'' Psych, hehe, gotcha! This is just a recording."
** Try to go to a floor that isn't critical to the plot, and you'll get this voiced message:
---> "Access denied. [[LeaningOnTheFourthWall This floor was never modeled or rendered.]]"
* The ''Pegasus'' remake has some pretty narmy acting if you get discovered by humans:
** If you go through the left door for the colony entrance on Mars, you're greeted by two guards who argue over who should capture you before they both decide to rush up to you like curious puppies.
** If you encounter the two female scientists in the World Science Center, they let out a "scream" and jump back in such a way that it looks like they're barely grasping the concept of acting.
** Likewise, if you attempt to leave Sinclair's office with his rifle, a scientist with a really bad hairstyle and glasses mistakes you for him, wonders why Sinclair is carrying his elephant gun, then realizes you're an intruder before running off and screaming for security while simultaneously asking them to not shoot the guy with the glasses.
* The commercial for the Translator Biochip, listing warnings written in various languages and what would've happened if you didn't get them.
** '''French text''': ''Wet Paint''
** '''Farsi text''': ''Slippery when Wet''
** '''Hindi text''': ''Cheap Meat''
** '''Alien text''': ''[[ArsonMurderAndJaywalking Restrooms located in Lobby]]''
* In ''Turbo'', [[https://youtu.be/wggO_QiygTE the inexplicable rock music]] that plays when you enter the first hallway of NORAD VI. Apparently, Poseidon firing energy blasts at you with no way for you to fight back warrants some SugarWiki/AwesomeMusic. Same case with Mercury in ''Pegasus Prime'' when he spots you down a hall in the World Science Center.
* The way Dr. Sinclair's robots in the first game are neutralized can be pretty hilarious:
** If Ares is peacefully neutralized by capturing his shuttle with the tractor beam, you open his shuttle door and he collapses after he mumbles his prime directive:
---> '''Ares:''' The alien ship ''[[ElectronicSpeechImpediment must be destroooyyyed!]]''
** Mercury sheds his human disguise and tries to walk towards you, only to collapse with a groan of defeat.
** While Poseidon's peaceful defeat can border on NightmareFuel with how he almost grabs you only to be held back by the two cargo arms, defeating him violently by overloading the pressure in the dock causes him to implode like a soda can as he falls to the ground.
---> '''Poseidon:''' My mission ''must not--be stoooooped...''
