Barry inherited the barbershop from Great Uncle Arpeggio.
There is minor modulation in his monotone mumbles.
It’s unclear if he is even aware of the ongoings
of “The Barbershop Quartet” gang, because
the coppers tried a lie detector and his answers always
came out the same. They even tried a micro-expressionist
but his face never changed.
If nothing else, they’ve got Barry for association,
or acting as a drone. But, if I had to guess his association with the gang,
I bet Barry just cuts hair
and hits a mean middle C.
