Burt on anagrams at Harriet:
The most famous acrostic in contemporary poetry is probably Paul Muldoon's "Capercaillies," a stanzaic poem about a romance gone bitter whose stanzas spell out "IS THIS A NEW YORKER POEM OR WHAT?" It's a prank, but it's not just a prank, since (as often with Muldoon from that period) the intricate games are a sign of frustration, even exhaustion, with simpler attempts at sincerity, collaboration, or connection of a kind that other people will understand.
Some new pangrams for you to try! The estimable Richard Polt adds a few of his own (in the comments), including the timeless "J.Q. Vandz struck my big fox whelp."
