A Lock on the Emergency Fuel Shut-Off Button? Genius

If there's one thing you take away from this list of D-I-Whys, it's that safety should always come above your pride. Sure, you might want to complete your home improvement project without enlisting the help of a contractor, but if this will affect the safety of yourself or others, you should probably leave your ego at the door and hire some help. This person definitely should have done that when installing this emergency shut-off switch.

Although this switch needs to be accessible to all at all times, the person who installed this decided to place a lock on it! Why they did that, we'll never know.

An Explosive DIY Grill

If you're looking to upgrade and renovate your backyard, why not add a fireplace or even a pizza oven into the mix? Of course, we'd always encourage people to buy a ready-made fireplace or pizza oven from the store - but some people don't like to play by the rules. This person obviously wanted a DIY challenge, which is why they decided to construct their own using some leftover bricks in the garage.

While this probably looked like a cool pizza oven when it was cold, things went south as soon as things started to heat up. This is the end result, and it doesn't look pretty.

When You Accidentally Leave the Paint Can on the Wrong Side of the Room

Most people are used to seeing footprints in the sand or even on the Hollywood Walk of Fame, but not footprints on the floors of your own home! But it seems as though this person found themselves in the midst of a real DIY dilemma when they finished painting their kitchen floor. Should they leave a paint-pot-shaped space on the floor, or should they bravely step on the wet paint to grab the pot? Well, we think it's pretty obvious which one they chose.

Thankfully, this DIY disaster won't take too much to rectify, but now we understand why so many people choose to hire painting and decorating contractors to do jobs like this.

A Bit Wonky

Could you live in this house? Well, we're going to assume that there are a few people reading this who couldn't live with something that's so wonky - and we don't blame them. If you're going to bypass using a professional contractor and undertake home improvement works yourself, you really need to put your time and effort into making sure it's perfect. But we guess this DIY wannabe was running late for an appointment when they fixed these lights on the wall.

The fact that this is off-center would bug us for the rest of eternity, but let's just hope that the person behind this DIY isn't quite as detail-orientated as the rest of us.
