“What are your grave misgivings about U.S. Grant, and what do they have to do with Leonhard Euler?”

[Derb] Sorry, I meant 28th, not 18th.

Notice the pattern here: I am falling one short in my leading digits: Euler’s 200th (should be 300th), Wilson the 18th Prez (should be 28th).

If only I could make this work with MY OWN AGE.
