The trouble with ketchup packets is figuring out where to put the ketchup. Do you put it on one of the flimsy brown napkins you get in your fast food bag? On top of the actual fast food bag? Into your mouth directly?? This is assuming that you're not waiting until you get home to eat fast food off of a plate, of course.

Twitter user Today Years Old posted a photo that is a serious gamechanger for the ketchup debacle. The tweet says, "Did y'all know the flap on your fries box actually has a purpose?" and, well, check it out for yourself:

I think the high end of the box is meant to for the workers to be able to grab the top without burning your fingers w freshly hot fries out from the deep fryer (scolding hot oil). But this can of course double as a dip corner. Just my thought! — kicki carlson (@eaglechirp) January 13, 2019

We decided to put it to the test, with a large order of fries from McDonald's. As it turns out, you can indeed bend the flap back to make a nice little platform for your ketchup. Is this the "real" purpose for the design of the fry box? Who knows! It works, though!
