Yea! Humor rules once again as the fab four return to their goofus roots. Though still writing, Gunnar has nearly retired, with just a couple of appearances as a guest vocalist. Joe Finetti is expanding the musical complexity with an additional palette of sounds not heard before. Historical note: Andrew Chaikin is the vocal percussionist on Mr. Duality. The Bobs have the courage to deal with common social afflictions such as sports autograph sessions (the reggae "Sign My Snarling Doggie") or "Spontaneous Human Combustion." Poof, there goes another one!
