People are watching these babies laugh hysterically and trying not to crack up themselves

Upworthy recently shared an adorable baby giggling video on our Instagram page (which you definitely want to check out if you're starved for feel-good stories) and people expressed gratitude for the instant boost of happiness. There's something so pure about babies expressing joy and it's nearly impossible not to get flooded with mood-lifting endorphins when you see it.

So we thought we'd collect some of the Internet's best baby laughs, since we can all use a little extra dopamine right now.

In addition to head bops, babies find certain sounds rip-roaringly hilarious.

Anyone remember the baby who thought that paper being torn was the funniest thing to ever happen? It never gets old. Paper rip equals baby laugh— right on cue. So freaking cute.

Seriously, why is paper being ripped in half considered the peak of comedy routines for the wee ones? This baby couldn't even stay upright. He found paper tearing so funny.

Pretty much any sound can make certain babies laugh. Why? Who knows. Maybe it's the unexpected aspect of it.

Wait until your old man starts making fart noises. Fart noises are universally funny and apparently our tendency to giggle at them is ingrained in all of us.

But it's not just noises. Apparently, something as simple as blowing on dandelions is next level hilarious for the baby set.

How about the baby who laughs at himself every time he gets startled? (It's impossible not to giggle at this. I've tried. It's seriously not humanly possible).

If one baby laughing is a delight, why not four at once? I can't imagine having four babies at once, but this video almost makes it look appealing, at least for a few minutes. And again, it's just a dad making silly sounds that creates the synchronized, double-stereo baby giggles. So. Much. Fun.

For the grand finale, even though this kiddo isn't technically a baby—more like a young preschooler—his laughter is so infectious and entertaining he had to be included. How much fun would it be to have this kid in class?

No matter how bad things get out in the world, the delight of babies and children enjoying the simplest things in life can always bring us back to a place of joy and gratitude. Anytime you're feeling down, pull up a baby laughing video. It does the heart good.
