Walloons have presented Luxembourg with a dual proposal. Firstly, they want full ownership of Les Thermes, in return for Glen McArthur 'Luxembourg.'
A Messancy yokel commented, "We're not Luxembourg, tourists don't buy that shit! Plus it's only Luxembourgers who shop there. Les Thermes on the other hand is basically just a breeding ground for Belgian scum. Let's trade!"
A Luxembourgish spokesman snorted, "Sure, throw in Parc Merveilleux as well".
The second proposal was to work via their smartphones while on the move between the two countries, to get around the latest double taxation laws. This was rejected immediately as they are basically doing that anyway. Minus the actual work. Often while wandering across the lanes of the highway.
