Denial. It’s not just a river in Egypt anymore, is it Harry?

Our reading
An editorial interpretation.
The speaker turns 'denial' into a sound-alike for the Nile, then directs the joke at Harry. A geographical pun becomes an accusation of refusing to face something. The teasing question makes the wordplay personal, while leaving the particular unwelcome truth outside the quotation.
