“Why do you have a banana in your ear?” I asked (yet a fourth time.)

Semantical:

Fashion & Ontology:
- Earbuds are SO last season! Buds become blooms. Blooms fall off, and are replaced by fruit... Voila! The earbanana!

Medical / Psychological / Sadistic:

- “Well, as Jesus said, ‘By their fruit you shall know them.’ ”

Proverbial / Buzzfeed:
- “ ‘An apple a day keeps the doctor away!’ You’ll never guess what a banana a day prevents!”

Experimental:

Adolescent / Historically-Unexpected:
- “Oh sure! Jill gets her eyebrow pierced; everyone thinks it’s cool!  Dan gets a tattoo; no one says a word! But *I* get a banana in my ear, and suddenly, it’s the Spanish Inquisition!”
                                   
Experiential:
- “You know how you can a hold a seashell up to your ear, and hear the roar of the ocean? When you put a banana in your ear, you can hear the sound of the jungle!”
(At night when the lion is prowling, that is.)

Traditional / Spiritual
- “I do this in accordance with the practice of my ancestors. My father’s father’s father, four generations back, stuck a banana in his ear – and so we have done in every generation since. HIS father before him used a zucchini – he had never seen a banana.”

Self-Promotional:
- “I’m starting a new fashion trend.”
