I'll steam-roll you!
You know, if there are mice in the bottles they can be exchanged at the Playero for free beer. It's actually part of the judicial code, but it's something most people don't take advantage of.
So Mike, if all you get back is two cases of empties look on the bright side.
All you have to do is round up 48 little mice (which should be an easy task for you, according to the poem you published), neatly pack them into the empties, hop on a motoconcho, exchange them at the supermarceto, and voila, you're back in business.
And if you are lucky enough to find a friendly and helpful Canadian, who is good enough to take the two full cases back to your apartmento, so much the better.
Just one more happy ending in beautiful downtown Sosua, eh?
