An Accordion Player Walks Into A Bar,

orders a drink and chats up the bartender and the regulars for an hour.

Suddenly, he realizes that not only has he left his instrument in his back seat of his car in full view of passers-by, but he hasn't even locked his doors.

He quickly excuses himself from his conversation and rushes outside and up the block to his vehicle to take care of business, but it was too late.

Sure enough, someone had thrown another accordion in his back seat.
