Dude, never fuck your eskimo sister in laws. That's almost incest.

The sacred sister law states that “If you find news or information that makes you feel uncomfortable, you must share it to your sister”.
The sacred sister law: Brit and char are sisters. Brit found a video about an onion that made her feel uncomfortable. Brit shared the video to Char.

The ultra important, high falutin, and just all around annoying sister of your spouse. She will not be at your wedding because she has more important things to do, and if by chance she shows up, she'll ruin it. She's your mother-in-law's teammate and soldier.
The ideal sister-in-law is one that resides six feet below the ground in a cemetery, right next to the ideal mother-in-law.
