Rives: The Museum of Four in the Morning | TED Talk | TED.com
Rives' first talk about 4 am, "The 4 am mystery."
This is a link to the poem he mentions near the start.
I can identify with Matt Groening as well, mentioned in Rives' talk (the first linked here) as, like me, "not a morning person" and seemingly as nocturnal as I am.
