Joan Rivers told TMZ she had a one-night "bounce" with Johnny Carson.
Rivers guest-hosted Carson's "The Tonight Show" for years, until the two had a falling out when she got her own talk show. The topic came up because it was reported Tuesday that someone is trying to sell a sex tape featuring Carson and one of his wives from the 1970s.
The reports also said that Carson wasn't just the biggest in, er ... name when it came to late night talk show hosts, something Rivers confirmed.
"I had no idea the man could stand and sit at the same time," Rivers said.
No, I don't really like thinking about any of this either. But we can talk about it, since it's the Internet and all.
Rivers said she wants to see the sex tape because she's curious who Carson's partner was. She wasn't buying the theory that it was one of his wives.
