Flag of Democracy (often abbreviated F.O.D.) is an American hardcore punk band formed in 1982 and originally from Ambler, Pennsylvania, a suburb of Philadelphia.
 The group plays a mixture of melodic punk, frequently with two-part vocal lines, and noisy, dissonant hardcore, often at extreme speeds – many F.O.D. songs push past 200 beats-per-minute.
 The band never attained commercial success, but enjoys popularity in certain underground circuits, particularly in Europe.
 They were referenced in lyric by fellow Philadelphia-area rock group the Dead Milkmen in the songs "Nutrition" and "Milkmen Stomp."
Pleaseeasaur (pronounced Please-ee-uh-saur) is an American comedic musical act made of JP Hasson (formerly in We’re Not From Idaho and Touch Me Zoo, both with Joe Genaro of The Dead Milkmen).
 The music is high energy camp style humor.
 The live performance usually includes Hasson in many costumes, each of which coincides with the song, along with multimedia animations of related images on a large screen.
 Many songs are commercials for fake companies such as "No Prob Limo", "Pizza Brothers and Sons, Inc." and "Action City News."
