Lenny is usually deft with attractive women guests so I wondered if we would see any spark between these two classic characters -- or if one would be repelled by the other's hunger for center stage or intimidated by the other's stature.

Success! Both rose to the occasion -- we need to hear these two together more!

Another great segment, congrats.

Kevin, it wasn't that Johnny Carson needed to give her permission. What hurt him was that she never even came to him to tell him what her plans were (i.e., give him notice)—after he had given her a tremendous job of being the permanent substitute host of The Tonight Show.

Up and coming comedians...Louis CK...??? Leonard shows his naivete - again!

Oh, that was hysterical! Great segment. Have her on again, soon!

Lopate & Rivers could bring back vaudeville!

I am falling off my chair laughing

Jerry lewis was pretty funny on the lopate show a few years back
Everyone should look it up in the archive

Harvey Kietel looks like a homeless person.

Crying with laughter! Wow!

First time I ever heard Leonard Lopate lose it on the air, breaking up laughing.

I do love Joan Rivers' work.

"cows tip her"

joan rivers is so damn funny. even her throw away lines crack me up.
loved her guest spot on "Louie" as well.

st. joan of hysteria! i'm so stealing that colostomy bag trick the next time i'm seated next to an obese passenger on a flight!

adore you, joan!!

Te adoro Joanie!

Still funny after all these years. Thank you!

Jewish self-hatred manifests itself first in changing names, then lots of plastic surgery, then disappointment with everyone else as well. Nobody and nothing is perfect.

Hi Joan,

I'm a big fan and admirer! I saw your documentary and watch Fashion Police every Friday night.

Question for you: how do you find time and energy to do all this?

Big hug and keep it up!

My "complaint" about the usually hilarious Joan is that she wears fur despite knowing the tremendous suffering those coats have caused to animals.

Please ask Ms Rivers for her opinion on Mayor Bloomberg's war on large non-diet soda, and her take on the Queen Elizabeth's Jubilee celebration.

i'll give her something else to hate,sure she can be funny at time; but rivers and rickles type of humour, is just kind of tired at this point. can i say kind of tired on WNYC,or is that too colloquial? btw- on your behalf,who the hell did johnny carson think he was, in expecting you to ask "permission",in order to get your own show on another network. what backward regressive feudal century, was carson living in ?!
