Some of the Whateley Universe characters have used their powers to dry off after a shower (Phase and Chaka both), dry her hair (Fey), shave her legs (Verdant), unpack suitcases (Bugs), keep her clothes clean (Pristine), have Snowball Fights (a lot of Poe cottage), mop floors and fold laundry (Chaka), paint a room (Plastic Girl), move furniture, shop, and on and on.
Jade's main trick is to split off independent telekinetic extra 'copies' of herself by 'charging' them into objects; when the charge runs out, the copy re-merges with her and both sets of memories integrate. So what does she quite naturally do? Attend two sets of classes at once and use the same trick to study/do homework/clean her room that much faster. Also, be able to go to the smelly parts of the sewers without danger (Copies can't smell!), work a neat costume, be able to keep an eye out for bullies, not need to use anesthetic...Jade is the MISTRESS of Mundane Utility! (Which often leads to ACTUAL utility!)
Happens occasionally with some of the SCPs of the SCP Foundation. Some examples include SCP-500, pills that can cure anything, being stolen to "cure a hangover"; a young woman who can see and manipulate locations depicted in pictures asked to "punch or stab people over the internet"; and a young man who receives visions about various objects (usually other SCPs) asked to locate lost wallets and keys. When such abuses are found out, the personnel involved are at least reprimanded, if not terminated.
Plus there are the SCPs who only have mundane utility (a pizza box that makes your favorite pizza & never runs out) and the ones that just look like have mundane utility but can have interesting applications, including a coffee machine that can give you cups of any liquid, including someone's blood.
The Foundation does discourage its personnel from using SCPs in this fashion. Mundane uses of the objects is highly regulated — even the pizza box.
SCP-294 actually isn't as regulated as you'd think. All the Foundation really needs for it are two armed guards stationed at it to make sure no one orders anything dangerous. Otherwise, they keep it in the break room, and allow people to use it to get beverages in order to save money on drinks. Hey, they've gotta cut some costs too.
Just remember that it doesn't understand euphemisms or slang, and order "a cup of coffee", not "a cup of Joe".
SCP-739 flips the molecular chirality of anything locked in it. One researcher pointed out that using this on sugar results in a pretty good low-calorie sweetener.
If it's large enough and got a thin, but strong waterproof case, you know someone will turn it into a boat. See the second picture.
In Red vs. Blue, members of the Blue Team have used the scopes of their sniper rifles as binoculars to spy upon the Reds from a distance. Also, in the later seasons, Tucker's sword also counts. It is debatable as to whether or not it was primarily created to be a sword or a key. Quoth Caboose: "Or maybe it's a key all the time, and it when you stick it in people, it unlocks their death."
On Orkinet, a Sister of Battle mentioned using an inferno pistol - a very rare weapon capable of melting TANKS - to flash-cook a fish.
Corridor Digital's Sync series involves a secret agent who can jump into a realistic android body. He uses it for covert ops, and to help him propose to his girlfriend ina a humorous manner.
Episode 3 features a young Chinese woman from Hong Kong who is a spectacular hacker and programmer. She uses her talent to try and write an iPhone app. And then hijack the local air control in order to fly planes over the houses of the girls who teased her and tried to break her computer so they would look like crap on school photo day. To do so, she got up to mischief with every computer and iPhone with a certain game in a 25 mile radius. Including that of the aforementioned protagonist's agency. The episode ends with her being caught and dragged into a car by that agency.
Zigzagged with Linkara. He uses his magic to turn his toys, (which include phasers, morphers, and sonic scredrivers into the real things purely for fun, uses his spaceship to threaten other online reviewers, and even uses his battlizer to burn a bad comic. However, their secondary use is as weapons against whatever villain invaded his universe.
Matthew Bounds from Phaeton is using his power all... of... the... time... and most of the other characters don't even notice it, which is probably why things turn bad when he is Brought Down to Normal. And he is not the only one to use his powers for mundane situations.
