It's possible this video was doctored, since we've never heard a cat pass gas (and the creator is already selling t-shirts). But real or not, farting has never been so adorable. [Buzzfeed, Farting Fat Cats]
So one time we were sitting around watching TV, and my sister's fat ass pitbull Atlas was sitting in front of us staring at the set. When he farted, his cheeks rumbled on the hardwood floor, and he let out the biggest yelp and ran around in confusion howling, then bolted out the door.
I loved that dog. RIP big guy.
