An airplane bottle of rum is just the right size for a medium Mango Julius.
Not that I would know anything about that, because I would certainly never take my Mango Julius into the ladies' room at the mall and spike it so I could enjoy a refreshing, fruity cocktail during a pedicure.
Neither would any of my friends. Especially not my friends who get pedicures with me.
I hear it's damn tasty though.
