File this under odd occurrences. Last night in late-night TV, Dana Carvey was a guest on Late Show with David Letterman and did all sorts of voices, reminiscing about "Chopping Broccoli" and Johnny Carson, and impersonating several celebrities.

Carvey also impersonated both Jay Leno and Robin Williams, and after he jumped around the set pretending to be Williams, acknowledged that if you had changed the channel just then, you might have been seeing Williams do his thing himself on Leno's show. Shhh. Don't tell anyone. But roll the clip! (The Williams bit starts at 9:11, btw) And if you'd like to see what Williams had to tell Leno, you can watch that here.


 

Carvey is a guest tonight on Late Night with Jimmy Fallon. And oddly enough, last night, another famous impersonator was on Fallon, as Rich Little was showing off his Johnny Carson. Wild. Wacky. Stuff. Now if Carvey pretends to be Little tonight, I won't know what to do.
