OTA -- a new twist to "call me when you land"

I heard a bizarre interaction this evening (about 8:00, on 126.4, near
White Plains, NY). The conversation went something like this:

NY Approach: Proceed direct Carmel.

Pilot: Carmel isn't on our route.

NY: It's on the SID. I assigned you the SID. [Note: I'm not sure what SID
they were talking about; I'm guessing it was the Westchester One]

Pilot: No, Carmel's not on the SID.

NY: Yes it is.

They went back and forth for a while, with the pilot insisting Carmel was
not on the SID and the controller insisting it was. Then, it got stranger.

Pilot: OK, tell you what, give me a phone number where I can call you after
I land.

I've heard controllers ask pilots to give them a call, but this is the
first time I've ever heard a pilot insist on calling. Things actually got
a bit more bizarre when, a few minutes later, the HPN ATIS was advertising
Mike and the controller was insisting that somebody should have November :-)
