My New Alma Mater

In the car on the way home from church, as my wife is listening to Car Talk on National Public Radio…
Grady: Mommy…is that N-P-R?
Amy: Yes, Grady.
Grady: NPR is Daddy’s college.
Amy: No, Daddy’s college is O-R-U.
Grady: No. It’s not.
Amy: No? Where did Daddy go to college, then?
[long pause]
Grady: Daddy’s college is C-3P0!
