Stargazy pie

This morning I spotted someone wearing this T-shirt:

This caught my attention because I had just posted about a homophone of pie in "The closest calendrical approximations of pi" (June 6).

At first I thought of pie as a diminutive ending as in cutie-pie (which used to be written as QT 3.14 on Usenet, for another pi link). Didn't Marina Gamba use to call Galileo her little stargazy-pie? Not until I ran an image search for the phrase to get the above photo did I discover that it's an actual pie -- a Cornish dish with fish heads sticking out of it as if gazing at the stars:

Fish and stargazing together suggest the constellation of Pisces, which includes pi in its name and Pi Day (March 14) among the birthdates for which it is the sign. The title character in Life of Pi is actually named Piscine, having been named after a swimming pool, and that French word derives from the same Latin root as Pisces.

Pi-sces sounds like "pie sees" -- and why would a pie gaze at the stars if it couldn't see them?

Sometime in the late 1990s I read a poem in a magazine (I think it was Writer's Digest) that was called "Pisces." The first part was about looking at fish in an aquarium, and the second part was about stargazing. It ended with something very close to "You are all I have / For an anchor / In a sea of fish and stars." I have scoured the Internet in vain for any trace of this poem.
