Tay Zonday’s scatological YouTube hit “Chocolate Rain” has already bred a slew of parodies, but John Mayer’s wins the prize for most hilarious interpretation. Watch here as he rocks an a cappella version of the gross but catchy tune (with comic actor Sherrod Small on background vocals and hand claps). The cover, hailed by Mayer himself as “keeper shit” (get it?) ups the humor quotient by drawing melodic inspiration from Nelly Furtado’s “Say It Right.”
