Sometimes genius is right in front of your face. The answer you've been looking for has been there all along. Just like Dorothy in The Wizard Of Oz.

You get your burger. You get your fries. How do you combine them for the perfect feast? Some tear open the ketchup and pour it all over the fries. That's a quick resolution but then the balance of fries to ketchup is thrown off. Some fries have too much ketchup; some not enough, or none at all.

Personally, I like to bring the fries to the ketchup, not the other way around. Years ago, I saw a guy squeeze his ketchup into the top lid of the burger box. That's certainly convenient, but the question has to be asked: "Who touched the lid before you did?"

I've never heard of someone contacting some disease from a burger box, I even Googled it. So I stared at the box, really hard and didn't see anything germs or anything crawling, I decided to live life on the edge and just went for it.

Now, the world is awakening to something that's been there all along. I introduce you to the "flap," If you order the large fries at McDonald's (and who doesn't), you'll be rewarded with a question and an answer.

Check the picture and you'll notice the top part of the fries container, or the "flap" sticking up higher than everything else. Simply fold back the "flap" so it resembles a shelf. Squeeze your ketchup into the shelf, and presto-change-o, you have the perfect place for dipping your fries.

Don't overthink this, and wonder if anyone touched the "flap" before you did and just take a walk on the wild side. Eat those fries like nobody is watching.

Once you know the secret of the "flap" you can perfect your fries to ketchup ratio. Now you know how Ben Franklin felt when he discovered electricity, or Thomas Edison when he invented movies.

Did someone at McDonald's design the fry box with this in mind? Or did some surfing stoner, stare at the box long enough, that it just became another one of life's truths?

You're welcome.
