There are people who, if they only had a slot, might turn a pretty penny
as moral try-your-strengths, like those we see in railway-stations for
telling people their physical strength when they have dropped a penny in
the slot. In a way they have a slot, which is their mouths, and people
drop pennies in by asking them to dinner, and then they try their
strength against them and get snubbed; but this way is roundabout and
expensive. We want a good automatic asinometer by which we can tell at a
moderate cost how great or how little of a fool we are.
