Comedienne Joan Rivers turned the air blue during a live interview on Good Day Sacramento on Tuesday morning after she swore at a host for cracking a joke about her daughter Melissa.

Is it just us or is Joan getting too old for this sh*t?

The 76 year old spitfire appeared on the local morning broadcast to promote her new TV Land reality show How’d You Get So Rich?, but things went horribly wrong after one interviewer made a quip about her 41-year-old daughter’s lack of identity and business sense.

“Ever run up to someone and say, ‘Hey, how did you get so rich?’ and the woman replied, ‘By riding on my mom’s coattails!’”

Joan cut the interview short – but not before scolding the male host with a barb of her own.

“I don’t think so. And I think we’re gonna end the interview right now. Don’t get so fucking smart,” she snapped.
