These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ear Worm: Most of the music, but the "Bunyan Ride" jingle is catchy as a mofo.
Fanon: Fans tend to call the protagonist Jacob, and the player 2 character Lisa. The official website never named them, and no names are given in the manual either. It appears that the names came about when someone added them to the Wikipedia page in July 2007, and the fandom ran with them. In fanart, Jacob is depicted with a red jacket, a green t-shirt with blue jeans and carries a flashlight, while Lisa wears a blue crop-top jacket, jeans and a purple-and-white hat.
Fridge Brilliance: While the ending still is rather stupid (see Crosses the Line Twice and What an Idiot), it makes sense that an arcade shooter would have an ending with an in-game explanation to how the next player to pick up the controller can play the game.
Goddamn Bats: Played obnoxiously straight. Also featured in the same vein as bats are maggots, spiders, floaty bug things, and LITERAL spider monkeys.
Most Annoying Sound: The survivors you find leave little to be desired out of their lines, which only consists of "HELP ME!", among other audio clips. It can get pretty grating and make you wish you could shoot them with no penalty.
The gigantic clowns in the Big Top make odd squeaking noises when they're hit.
