I went into Gus's artificial organ and taco stand. I said "Give me a bladder por favor."

Our reading
An editorial interpretation.
A shop combining artificial organs and tacos makes an unlikely purchase sound like an ordinary food order. The request places bladder beside the polite Spanish phrase por favor, which also invites a playful resemblance to a more familiar order. The joke depends on that strange pairing of merchandise and language.
