Joan Rivers revealed on GMTV that she’s worked with some stupid people in her lifetime, and Angelina Jolie’s one of them.

Talking about her new London show, A Work in Progress By a Life in Progress, the comedian revealed she was surprised to be working alongside intelligent actors:

“I’m finding actresses are smarter than I thought. Well I’ve worked with stupid actresses – I’ve worked with Angelina Jolie – she saw a sign that said ‘WET FLOOR’ one time, and she did. I mean she’s attractive, but not a bright girl. Stunningly beautiful but stupid… she would have asked Stevie Wonder, ‘What’s your favourite colour?’”

Speaking about members of the opposite sex, the 75-year-old American stand-up revealed Scottish men are off the menu: “I love the Scots, but you don’t know who’s gay because they’re all in a dress.”

Joan also revealed she likes to unwind by being around her grandson. “It’s great having him around, unless I’m wearing white,” adding, “He calls me ‘Nana Newface.’”
