"Hail, Hail, the Gang's All Here" is a song from 1917 that uses the tune from "With cat-like tread, upon our prey we steal" from The Pirates of Penzance. One line from the song is sung by the Singing Weatherman in the Veterinarian's Hospital sketch from episode 516 of The Muppet Show. Operating on their patient without a roof over their heads, Nurse Piggy observes that it's beginning to hail. Dr. Bob asks, "Hail?" (the weatherman finishes) "hail, the gang's all here / what the heck do we care..."
