From a reader:

Mr. Goldberg,
Was wondering why the NRO homepage is so bare and why the Corner is so silent. Then it hit me: today is Dominion Day (AKA Canada Day)!
Which leads us to this Simpson’s reference (from memory so forgive the paraphrasing):
CN Tower Worker: The tower is closing folks.
Homer: Really? (Waves a dollar in the guy’s face.)
CN Tower Worker: An American Dollar! What time would you like your wake up call sir?
