In 2004, Da Capo Press published their exercise book, Punk Rock Aerobics. In February 2021 Hilken starred in a Green Day video “Here Comes the Shock” doing her Punk Rock Aerobics.

 In 2012, Mancini formed “The Monsieurs”, a garage punk band, with Andy Macbain (Tunnel of Love) and drummer Erin King.   The Monsieurs have released two full-length albums (The Monsieurs and Deux) and several singles on the Slovenly label.
