Finding Taylor Swift Before Your Hairline

Hey, listen up, smooth-brain. This joke is a savage burn about baldness. Taylor Swift is super famous and rich, so she's never just "on the streets." The joke uses this extreme improbability to say that finding your receding or lost hairline is even *less* likely than spotting a mega-star chilling curb-side. You probably write notes to yourself in crayon, don't you?
