This movie? -- You can call me RJ, or you can call me Robert James

I remember this show, the one with Fred Savage. I'm just curious if this is also contained a part where some kid(s) go(es) to a museum and someone at the museum goes on about "Oh, I'm Robert. But you can call me RJ, or you can call me Robert James, or you can call me Robert J, or you can call me R James, or you can call me..." and on and on. It may not have been "Robert James," but the point is that some museum guy in a dinosaur film/show goes on and on with about a billion different names "you can call" him.
