A man walks into a bar with a slab of asphalt.

This joke lands its punch by cleverly hijacking a common phrase. The punchline plays on the double meaning of "one for the road," which we all know as an idiom for a final drink before a journey. The humor is powered by the absurd visual of a man treating a piece of pavement like a drinking buddy, forcing us to take the well-known expression completely literally. It’s a classic bait (Review)-and-switch built on simple, effective wordplay.

The expression itself has a long history, likely dating back to the days of coaching inns when travelers would have a last drink before continuing their trip. It was immortalized in pop culture by the famous Frank Sinatra song, "One for My Baby (and One More for the Road)." By bringing a physical "road" to the bar, the joke masterfully collapses this entire cultural history into a single, silly image, making it a perfect, groan-worthy gem.
