One of the funniest things is when you try to pet your animals, and they all start running around in a circle as if they're playing a game of chase. It's chaos but in a really cute and funny way.
Another aspect could be the relationship with her partner in the fanfic. If she's married in the game, her spouse would play a crucial role. They could be very protective, go with her to doctor appointments (if there were such a concept in the Stardew Valley world), and start planning for the new addition to the family, like building a new room for the baby.
In ophthalmology, sometimes patients bring in the most unusual eyewear for repair. I heard of a case where a patient brought in a pair of glasses that had been taped together with so much duct tape that it looked like a strange art project. The optician had a hard time not laughing while trying to figure out how to fix it.
Meeting really eccentric characters can be very funny on a trip. I remember meeting a man who was traveling with a pet parrot on his shoulder. He told us all kinds of wild stories. Also, transportation mix - ups are hilarious. Like when you think you're getting on a luxury train but it turns out to be a rickety old one with chickens on board.
When you go to a food truck at night and the vendor is doing some really wild food - making tricks. For example, I saw a guy making pizza dough and spinning it so high in the air that it almost landed on a customer's head. Everyone was both amazed and laughing at the same time.
One funny thing is when the TV in the hotel room has a mind of its own. I was trying to change the channel and it just kept switching back to a soap opera no matter what I did. Another is when you open the mini - bar and find the strangest items like pickled eggs or some really old - fashioned candies.
One funny thing is when a girdle is mis - sized. Like if it's too big, it might keep falling down. I knew someone who wore a girdle that was too large for her at a wedding. She had to keep pulling it up during the ceremony, which was really embarrassing but also quite funny in hindsight.
In a marriage, sometimes the way a couple argues can be funny. For example, my neighbor couple once had an argument about what to have for dinner. They started making really exaggerated points about pizza vs. burgers, and they ended up making each other laugh instead of being angry.
One funny thing is when a customer falls asleep while getting their hair dyed. They wake up with a strange color on part of their hair because they moved in their sleep. For example, a guy once woke up with bright pink patches on his head instead of the planned blonde.
One of the funniest things is when people use the wrong tools for the job. Like using a butter knife as a screwdriver. It usually doesn't work well and can cause all sorts of chaos. For example, the 'screwdriver' might slip and scratch the surface.
One funny thing is when the TV remote has some really strange buttons or doesn't work properly. I was in a hotel room once and the volume button on the remote would only go up, not down. So I had to keep unplugging the TV to turn it off and on again to adjust the volume.
