Words have meaning. Grammar has a purpose. The joke-teller is necessarily within the store making a call to an unspecified “her” for unspecified reasons and we know this via the rare skill known as reading. Just because a vocal plurality of people interpret a Rorschach inkblot test or a Jackson Pollock painting as a specific message, that does not make those pieces mean anything, let alone any specific one thing or analogous things.
“call” is a transitive verb.
“from” is a preposition.
