What would the internet be without a healthy supply of amusing (and sometimes borderline stupid) viral challenges to keep us occupied for hours at a time? That wouldn't be the 2017 we know and love. And, of course, the best kind of challenges are the ones that put the YouTubers we admire in some kind of discomfort or pain.

Few challenges accomplish that goal quite like the extreme candy challenges of the interweb. Whether it’s weird candy, sour AF candy, or candy that taste like garbage, here are 11 of the candy challenges we can't get enough of.

Sour Candy Challenge

One of the more brutal candy challenges are the sour candy challenges, in which the willing challenger taste tests different types of super sour candy. And as you'll see by the expression on Collin Key's face, it really is as painful as you're imagining. Ouch.

Gross Chocolate Bar Challenge

Chocolate bars are meant to be creamy and delicious, right? Well, not if you're attempting the gross chocolate bar challenge, like YouTube channel MMG. Let's just say we're glad we're watching this one through the safety of our screen, because pizza-flavored chocolate is the only time those two all-time foods shouldn’t be together.

Bean Boozled Challenge

If you want to be entertained Harry Potter-style, you'll love the Bean Boozled Challenge. In this Muggle version of Bertie Bott's Every Flavored Beans, these candy beans come in same-colored pairs. YouTuber Rosanna Pansino could either enjoy pear flavored or booger flavored – the chance is hers to take and yours to watch.

Spicy Gummy Pepper Challenge

We know what you're thinking. "Why would anyone make a gummy, something that’s supposed to be delicious and sweet, in a spicy pepper flavor?" The answer is simple: so YouTubers like Wassabi Productions can try said spicy pepper gummies in front of a video camera. Thank God for Amazon.

Weird Candy Challenge

Candy is supposed to be sweet and indulgent – unless you're doing a weird candy challenge. In which case, Reese's and Twix need not apply. Watch Keion and Kianna of BFvsGF try everything from booger candy to scorpion lollipops, all from the comfort of your home.

Gummy Food vs. Real Food

One of the biggest YouTube challenges of this past year has been comparing real food with its gummy counterparts. For instance, partners each choose a platter – under one is a real cheeseburger and under the other is a gummy burger, and whatever you choose you have to eat. Let AzzyLand show you how it's done.

Japanese Candy Challenge

Everyone knows that Japan has the coolest, most out-of-the-box varieties of, well, everything. As Collins Key and his little brother found out, that includes some of the most interesting types of candy around. We're not sold on all of them, but some are V kawaii.

Giant Candy Challenge

Now this one doesn't sound so bad. Rosanna Pansino and one of her friends have selflessly taken on the giant candy challenge, in which they try to guess which gigantic candy they're about to bite into while blindfolded. None of the candies are gross or painful to eat, so that element is gone, but it's still fun to watch and crave everything from a distance.

Kissing Candy Challenge

An excuse to eat candy and smooch your S.O.? That's the kissing candy challenge that's been sweeping YouTube. What it entails is that you pop a candy in your mouth, blindfold your partner, and give them a kiss! Based on the kiss, they have to guess the candy. Marissa Rachel and bae demonstrate how simultaneously hilarious and awkward this challenge can be.

Warhead Smoothie Challenge

In a nutshell, you make a smoothie out of as many Warheads products you can get your hands on and chug it. JustJordan33 brought her sister into her video challenge so they could do a double challenge: whoever can drink the most of their super sour smoothie wins. What do they win? A great deal of pain and the honor of besting a YouTube challenge.

Chocolate Bar Challenge

About three years ago, one of the more popular candy challenges was trying to finish a giant chocolate bar without vomiting. While many YouTubers failed miserably at this task, you can trust professional competitive eater Matt Stonie to conquer this 1 lb. Snickers bar challenge – in good time, too!
