Our favorite late night hosts paid tribute to Joan Rivers who passed away Thursday at the age of 81.
JIMMY: "Besides being a pioneer for women in comedy, for everyone in comedy, Joan was a very lucky person because she loved her job so much, she never wanted to stop and she didn't have to stop because she was so great at it."
SETH: "I haven't been doing this job very long but I've not sat next to anyone who told more jokes faster than Joan Rivers when she was here."
JIMMY: "We had her on our very first tonight show when I took over."
JIMMY: "She came out and she came over to me and started crying and gave me a kiss. It was really emotional and really nice."
CONAN: "It's hard to explain to people today what an event that was. She would go on, she would guest host for Jonny Carson and everybody ... people would gather in the living room."
CONAN: "At that time, she was so, so outrageous."
LETTERMAN: "Talk about guts. She would come out here and sit in this chair and say some things that were unbelievable.
FERGUSON: "Ah, we lost Joan Rivers today, one of the all time greats. Yes, it's terribly sad. I just hope that when Joan meets the man upstairs he's wearing something she can insult."
