“Hysterical. She was great on on the radio. She was great on TV. She’s just great all around. And I’ll tell you, it saddens me,” Piscopo said.

“She was a real pioneer. A really funny lady,” Trackman said.

In 2009, CBS 3 Anchor Ukee Washington caught up with Rivers in Philadelphia.

“How many times do you go into a neighborhood and see one of those big houses and you go, ‘Who are these people? How’d they get so rich?’ Or I stop cars, which I’ve been doing today, a big limo pulls by and I go, ‘Who is that? How’d they get so rich?’ So I ask them,” she said.
