Lots of gas
Yeah, we had no choice but to add this one to the list for all of you fart joke lovers out there. As you can see here this kid is really going for it and pushing as hard as he can to get all that gas out. If your farts look as smoky as this you should really go to a doctor.
In the background, you can see a smokestack and some type of factory in the distance which would explain everything. But for the sake of having some fun, let’s just say it’s his farts and he is some sort of freak of nature. We hope he doesn’t pass out after this.
