It's unclear from the gif exactly what they did insider the freezer to make this work, but we're assuming they turned off the ice maker, dumped a bag of frozen pizza rolls into the ice container, and made sure the ice size was set to cubed before dispensing them. Just imagine what would happen if they switched it to crushed, and worse yet, the freezer burn on the delicious pizza rolls after sitting in there a while without the protection of packaging. Oh, and don't forget all the crumbs that'll inevitably built up in there if you're not careful.
A little over a week ago, a woman shared her own genius refrigerator hack, which essentially turned the built-in water dispenser into a wine dispenser. Of course, it's worth noting that such modifications could potentially ruin your perfectly good -- and probably expensive -- fridge, so you might want to be careful should you decide to tinker with it, too.
