Mr. Cliff, Jethro's graduating from the sixth grade, isn't he?

That's right.

Then he has to go through at least six more grades.

Six more?

Yes.

Another 12 years, huh?

Well, with my help, I think he can make it in six.

Then, of course, he'll go on to college.

College?

Gee whiz.

All I want to be is a brain surgeon.

I think you'd better change that ambition, Jethro.

To be a brain surgeon requires four years of college, four years of medical school, one year's internship, and from two to five, years of residency.

Oh, no.

Uncle Jet, I just think I'll settle for being an atomic scientist.

That might take almost as long.

Jethro, you got a third choice?

Oh, yes, sir.

Streetcar conductor.

Excuse me, I'll get that.
