"Jim Henson appeared on Rivers' talk show as a guest with Kermit. Kermit responded to Rivers' racy late-night conversation by reminding her that he was from Sesame Street." ^{[citation needed]} —Scott (talk) 03:13, 23 February 2007 (UTC)

Well according to the ever-reliable IMDB, and a handful of other sites out there, Kermit/Jim Henson was actually on a talk show she did in the UK, which was called "Can We Talk?" and apparently aired for 6 episodes, or one series, in early 1986. No details about what happened though. -- Wendy (talk) 03:43, 23 February 2007 (UTC)
