Dana Carvey came back to Late Night with Jimmy Fallon on Tuesday night, and Carvey and Fallon had fun talking about impersonations and exchanging back and forths and back and forths and you know whats.

You know what? Just watch these clips.

Here is the first part of Carvey and Fallon talking.

This is the Fallon impersonation of Charlie Sheen they were just talking about, in which Fallon pretends to roast his co-workers in a fairly dead-on version of Sheen. Kudos. Roll it.

And here is more, with Fallon telling Carvey he’d do impersonations of Carvey’s impersonations. Just in case SNL needed a kid understudy.
