We all do it, but why? Hank explains the whys and hows of our gaseous emissions.

So eating and drinking too fast leads to more burps and farts? That means two of my ex's biggest complaints were really the same issue all along! XD

I just banked $28 on Subbable for SciShow and saw that they had the Apocalypse collection signed by Hank. I bought it with my credit :3 so I felt special when he thanked the Subbable subscribers :)

Now I shall ruin Christmas dinner by explaining why exactly we fart :D

I have extremely loud, long farts, but they don't smell, at all. I do get those little ones right before having to poop that smell horrendous.

I farted twice while watching this video. I had to pause it and come back 10 minutes later to see the end.

Can you talk about the tape-worm and how its cyst manages to evade the immune system ?

2:52 An interesting segue into a video on how sweat itself doesn't stink it is the bacteria that grows in the areas that sweat a lot that causes sweat to stink.

I was watching SciShow during dinner... o_o;
Wait, since farts are 7% methane is that why people try to light them on fire?

Hank: "Crew, say noise!"
Crew:
They really know how to follow instructions XD hahahahahahahahaha

So every time someone burps, I should thank them for getting it out before it became a fart?

He's like a rock star of nerds. To quote Triumph, it's like some kind of super nerd! (Meant as a complement)

Has anyone else had it where your stomach makes a rumbling noise so loud it sounds like a fart, but it's not? I some times get these AFTER I eat, not before, so it's not from hunger but I didn't think digestion could be that loud.

[RandomGameplayVideos]

I burped 5 times while watching this video, from Coca Cola.

[thampire]

I farted 3 times while watching this video.

[Shystichu]

Ironically, I'm sitting here quite gasey

[Duros]

watching this after eating 2 cans of wonder if i can power my cooker with the gas.

Oh my god.  Best christmas present ever!
