In Stardew Valley one of the questions the game asks during character creation is “what is your favorite thing?” where you can type anything you deem fit for you (and your character). Without knowing why it asks this (or completely knowing why) means that an honest answer like “tits” can happen organically or specifically just for the chuckles.

Throughout the game, every time you find a Stardrop that increases your total energy bar, you are reminded of whatever favorite thing you entered at the start of the game.
