Kris Jenner and mother Mary Jo Shannon share medical marijuana together, followed by giggles and heavy snacking, in a clip for Sunday's new episode of "Keeping up with the Kardashians." Shannon was given the prescription for back pain, and suggests Jenner does it with her for her neck pain.

"I think you should do it with me. It is not a bad thing, they have obviously made it medicinally for people with AIDS and cancer and it's a good thing," Shannon says to her daughter.

"I'm not against anybody getting some pain relief from medical marijuana, that's the whole point here," the Kardashian matriarch explained.

"So if it helps my neck and she's asking me to do it with her, I'm here to support and I'll do it this one time. I never thought in a million years I'd be doing this with MJ."

They take the medicine in gummy bear form, which Shannon says tastes just like normal gummy bears, and Jenner says to her, "I don't like to drink alone so I'm sure you don't like doing this alone."

It's all fun and games until Bruce Jenner comes home, and is far from amused by their antics.

"We thought it be a good idea for MJ to try out some MJ, you know what I'm saying? You know what marijuana is?" Kris asks him.

"Yes, I do, and I won't have it in this house. I want that s**t out of the house," the former Olympian replied.
