Dan posted last week that the collect:, detect:, inject:, reject:, select:
suite was inspired by Arlo Guthrie's "Alice's Restaurant Massacre":

"They got a building down New York City, it's called Whitehall Street,
where you walk in, you get injected, inspected, detected, infected,
neglected and selected. I went down to get my physical examination one
day, and I walked in, I sat down, got good and drunk the night before, so
I looked and felt my best when I went in that morning. `Cause I wanted to
look like the all-American kid from New York City, man I wanted, I wanted
to feel like the all-, I wanted to be the all American kid from New York,
and I walked in, sat down, I was hung down, brung down, hung up, and all
kinds o' mean nasty ugly things. And I waked in and sat down and they gave
me a piece of paper, said, "Kid, see the psychiatrist, room 604."
