A joke about the difficulty of recruiting of executioners. Being a member of a firing squad is likely not a popular job, and so instead of getting qualified people, this prison appears to be handing a gun to anyone willing, even a dog. The person about to be executed nonchalantly quips that they can't find qualified people.
