An example of an anapestic poem?

All limericks are anapestic. Additionally, most of Suess's work is specfically anapestic tetrameter, like "The Zax" and "Yertle the Turtle," as is Charles Clement Moore's "The Night Before Christmas."

Interestingly enough, "Dazed and Confused" by Led Zeppelin also seems to be almost entirely anapestic tetrameter as well.
