It's been over a year since I saw URINETOWN, so I can't give you too many specifics; but at the end of "Snuff That Girl," the ensemble cast pose in a Fosse-esque tableau that is very reminiscent of CHICAGO.
-- "Run Freedom Run" is a spoof of GUYS AND DOLLS' "Sit Down, You're Rockin' the Boat."
-- When Ms. Pennywise announces that Hope is her daughter, she raises her hands in a fashion that recalls EVITA's "Don't Cry For Me, Argentina" scene.
-- I know that there's a FIDDLER spoof somewhere in the show, but don't remember where. At the very least, the curtain call (both music and choreography) resembles the Bottle Dance from FIDDLER.
