A few years ago, Piperboy84 very kindly flew me in his lovely, bright-yellow Maule from Santa Monica to Camarillo for lunch.
Taxiing out for the return flight, the Tower gave avoidance instructions to an incoming Cessna:
"Taxi behind the yellow Cub".
However, the woman in the Cessna was having none of that:
"Er, taxi behind the little yellow airplane."
So it's true - all light aircraft are Piper Cubs.
