Certainly Figaro in LE NOZZE DI FIGARO. (And yes, I do think that should be sung by a bass-baritone, rather than a baritone.) Also, Fiesco in SIMON BOCCANEGRA. I'd love to be a bass for an evening just so I could sing "Piango, perche me parla."

For bass-baritone, John the Baptist in SALOME. Not the longest role, but a great one.
