Wagner Tuba 

A fucked-up musical instrument most frequently heard in the works of Richard Wagner and Anton Bruckner. Though capable of sounding quite beautiful, it usually sounds like shit and elicits dirty looks and sighs from the rest of the orchestra.

Musician #1: "What are we playing on tour in March?"

Musician #2: "Bruckner 8"

Musician #1: "Oh Fuck! Wagner Tubas!!!"
