No matter how much you wipe there is still poop

Brain now naturally resists sleep for as long as possible, so everyone stays awake for two or three days before crashing uncontrollably.

Hot beverages are always either too hot or too cold.

This'd likely a bit more than inconvenience, but honestly, to the degree that it would be more than that (or more accurately to the people to whom it would be more than that), I just don't give a shit.

Make it literally impossible to knowingly lie. Full stop.

There’s always just a little bit left while wiping. You can never get it completely clean.

At random times whenever you are traveling in any vehicle, you simultaneously feel a sneeze coming on, and yet have to pee a little bit too. However, you can neither sneeze nor pee until you are out of the vehicle.

Inconvenient on a bus/train or as a passenger, deadly if you're driving. Bicycles are right out, I suppose.

Make flashlights scream when you turn them on.

Have every squeeze of tooth paste contain an air bubble that spews a bit on you.

Have a single dead pixel in the center of every display.

Make fridge doors not close automatically.

Make cars moan, whether ICE or electric.

All mouthwash turns to orange juice after brushing your teeth

I would give everyone noclip mode.

Convenient because you can fly anywhere and through walls. People's commutes would be so much shorter! You could visit any country you wanted without even needing planes. Everyone would experience an unprecedented level of freedom.

Inconvenient because of the messy implications of getting stuck in walls if you turned it off at the wrong time. Also people would probably just be able to take anything they wanted without repurcussions so the world might devolve into chaos. You wouldn't really be able to jail anyone. Security and privacy would be hard to come by.

Everyone has to skip instead of walking.

Thumb and ring finger change places. Opposable ring fingers.

Sex is painful for the man too

Make everyone listen to 10 hours of cow sounds on repeat.

Clothing sleeves, pant (trouser) legs, underwear garments, socks, etc. all have one side slightly longer than the other

I wish for water to no longer be a bipolar molecule

change the date system to day month year

Every time you drink anything or are near running wather youl get splashed in the groin and would look like you peed yourself.
