This trio of talented, loveable goofs continues to prove their cachet with a ridiculously star-studded cast on their third release -- because what's a hip-pop album nowadays without a boatload of guest appearances? But maybe more fascinating than Kendrick Lamar rapping about low-risk 401Ks, Billie Joe Armstrong playing mayor of NY, or JT and Gaga clarifying ménage à trois etiquette are the nonstop pop-culture references, from Indiana Jones to Oprah to George Orwell to Shamu to Urkel. That means multiple listenings are required to absorb all the absurdity. Challenge: Figure out "Spell It Out."
