Brains can't understand what's going on in these photos. Takes a minute

Sometimes the best things happen when we least expect them to. Nowhere is this more obvious than in the well-timed photos online that capture the perfect moment.

From accidental optical illusions, to just straight-up hilarious moments of happenstance, perfectly timed photos dominate the internet.

Here's just a small collection of the best perfectly timed pictures - pictures taken at the right moment that are guaranteed to make you look twice.

Follow The Light

The toilet bowl is summoning you to experience something of a lifetime. Would you want to find out?

Or, the toilet is trying to tell you about the most incredible experience that it has ever had.

A Beautiful Day

Sometimes, you just need to take a seat and enjoy the weather. It gets tiring walking around all day, you know?

But be careful what you sit next to. You could get mistaken for something else!

Fire In The Hole!

What a lovely day to let loose. No one else is around, so why not?

I’m sure this guy feels relieved after this. You can’t hold it in forever.

That Sucks

Just your average Starbucks van delivering their products. It really is quite the excursion.

So much so that the delivery driver is trying to tell someone how he feels inside. We get it, it sucks.

I Don’t Think That’s Allowed

Sir, I don’t think this activity will take too well once your wife sees what’s going on.

Maybe don’t urinate on your daughter, just a tip. There’s a better way for her to cool off.

Just Do It

Thrill-seekers aren’t always prepared for what’s to come. They can get caught off guard sometimes.

You made it all the way to the top, why not just do it? What could go wrong?

Twin headed monster?

Calm down, it's not a ferocious beast. It's just two pups playing with each other on the floor. I bet they are loads of fun.

That kid looks pretty old.

If you can't figure out what's happening here I will let you in on it. Look closely at the nose and mouth. You can see where the angle of the child's face makes it look like the lower portion of his dad's face is actually part of his. Mystery solved.
