There was a local Chicago band called "Uncle Funky Pants". Always made me laugh when heard it. My first band in HS was called "DiffStick" until one of my bandmates' dads figured out what we were up to. We were gearheads and had told our moms it was car-related when asked. Now a band without a name, were were sitting around listening to a rehearsal recording of a cover we were working on when the lead player said "Man, that was just No F***ing Good". The bass player replied "Yeah we're really NFG" ... and the name stuck. Told the parents it was our favorite chord progression. Fortunately, they weren't musical.
