As Martha Stewart shows Joan and Melissa Rivers how to prepare hanger steak with shoestring fries, Joan can't resist taking a jab at actress Kirstie Alley on 'The Martha Stewart Show.'

"Did you ever have Kirstie Alley as a guest on the show? Because she would just eat it raw. She wouldn't even wait," Joan said, pretending to lick the ingredients from a bowl.

Melissa then points to her mother's antics as an indication of what it's like to live with her on their reality show 'Joan & Melissa: Joan Knows Best?'

"You have to laugh all the time, Melissa," Stewart chided.

"I do laugh a lot. I laughed hysterically when she barged in my bathroom and took pictures of me in the shower," Melissa said sarcastically, referring to an actual moment from their show.
