Simply put, no. Really, the idea of a world without mustard doesn't even make sense. Think about it... what else would fill the nasally void? What else provides such versatile flavor? Mustard has always been the most beautiful thing on this entire planet. Mustard will always be the most tasty thing in the universe. Sure, mustard alone is questionably tasty. But mustard doesn't work alone, must amplifies other lesser flavors. Even those who claim they don't eat mustard are just fooling themselves. Remember homeopathy? Well, pretty much everything is home

opathically contaminated with mustard, and mustard has brought their food greatness.
Donald Trump thinks he can make America great again. No, he alone cannot. But mustard can.
We should not build a wall. We should build a ♥♥♥♥♥♥♥ mustard waterfall. Niagara Falls?
How about Mustard Falls? This is the only way to make mustard great again, scientifically proven in exactly 0 controlled trials, in eπi +1 peer reviewed journals.
Why would this make America great again? Imagine if you could take any boring sandwich and slather it in mustard just by putting it outside. That's right, we're going to make mustard rain.
The whole world would be spiced up a notch. Bland sandwiches would be edible again. Decent sandwiches would be mindblowing. Productivity would skyrocket a whopping 10,000% with all the newfound enthusiasm for life.

South Korea and North Korea would be friends again. Israelis and Palestinians would stop killing each other. Instead, they would all revel in their love of mustard.
Long story short, mustard not only binds this world together, but is the solution for all of this world's problems.

Burn on, my friend.
