Also on the first game, there's the opening narration with Flumpty nonchalantly explaining how he's immune to the plot and is coming to kill you, then finishing it off by telling you to figure out the rest on your own and "have fun". Needless to say, this can urge a few laughs.
One of the headlines on the newspaper that the Beaver is holding tells you that you should be watching the cameras.

Touching the clown's nose on the poster gives you the voice of a man (Jon himself!) saying the word "Honk". The tiger's head similarly gives you a flat "rawr".
Touching the cactus causes it to reply back, flatly telling the player that, yes, it is a cactus.
The developer's commentary reveals that the reason for all these objects in the room is that Jonochrome asked a friend what kind of things they'd put in an office like this, and they proceeded to give an off-kilter but on-brand nonsensical list.
The sound Flumpty and his friends make when they jumpscare you also gets a mention. You'd expect little from a game featuring a time-bending egg and his bizarre assortment of friends, and you'd be right with how they shout at you in such a shrill manner!
One Night at Flumpty's 2:
Occasionally when you start the night, a screen of a poorly-drawn Birthday Boy Blam appears, looking derp-faced.
There are also poorly drawn pictures of Flumpty holding a gun saying "Bang bang, y'all", and Flumpty standing next to a grave. Said grave reveals why the Beaver from the first game isn't in the second: He fell into the toiletand died.
The jingle in the second game. The cheerful Lyrical Dissonance is enough, but the pitch dropping and rising every second or so as it plays on the record player really sells it.
The dialogue box warning about the Redman's appearance: a picture of Redman with a loading screen and "INCOMING", with a "CANCEL" button underneath, as though Redman were just an incoming email coming from an annoying person.
You can find a cactus in every game, which when clicked, says "I'm a cactus." The third game is no exception, though the cactus's audio is so crushed it's nearly impossible to make it out as its signature catchphrase.
In CAM 2, you can occasionally see Birthday Boy Blam T-posing his way into the next room.
How does the game explain away the Owl's death, so that the Beaver and the Owl can be combined? Well, apparently the Owl choked on a urinal. No, not an urinal cake, the urinal itself.
Skull Flumpty when he gets at the central door in Flumpty Night. Admit it, he looks like a reaction image. Even his retreating animation is memeable.
Flumpty copying the Redman's trick from the second game, and the ensuing error message if he manages to shut down your cameras.
Power Flumpty, while a nuisance, makes a rather goofy face before he throws the switch. It looks like he's holding back laughter.
Flumpty's jumpscare is by far one of the most horrible ones in the series visually, but the sound? The same shrill little gargle that everyone made in the first game, with only the sound of Flumpty's grinder-like mouth to differentiate it.
