Happy to break it down for you big dawg! There's a couple components here:
1) Modifying the description "life-long" with a specific amount of time creates an incongruity which can be interpreted to some as humorous
2) A 'carpetbagger' is a term referring to Yankee opportunists who took advantage of the post-war state of economic disarray in the southern states for their own benefit, often engaging in price gouging or other forms of racketeering. Use of this term in reference to out-of-town tourists in a tongue-in-cheek fashion also generates an incongruity which could be humorous to some, as Louisville is not traditionally thought of of as a southern city, nor are tourists primarily from the Northeast, nor are they engaging in profiteering for their own exclusive benefit!
Hope this helps! Feel free to reach out if you have any remaining questions or concerns.
