From a reader:

Jonah,
I am not really a T-shirt kind of guy…but I make an exception for NRO.
Which means I am eagerly awaiting the opportunity to purchase the uber-NRO-dork shirt which is surely soon to be released:
“NRO: On account of the flies.”
Simple. Classy. Baffling to the masses. I’ll take two.
Cheers,
Kevin
