What does this even mean? Am I OOL or is this just a deranged post with 4000 upvotes

Both sides were sure they wanted the bridge destroyed rather than see it fall to the enemy. We were on the wrong side of the Sûre. Between the Frenchies and our platoon we had forty, fifty men, which wouldn’t be enough to stop the armored Gerries only minutes away. But we were determined to leave not one of us behind. It just so happened that two years prior I collaborated with a harlequin from Moulin Rouge who was in a secret order descended directly from Chicot the Jester. They were dire times, and against his oath, he taught me secret clown techniques lest such lore, forbidden to non-clowns, would serve the resistance. That day at the bridge, I used clown car packing technique. We were able to fit all the men into a single utility Jeep and race across the bridge moments before it was destroyed in front of the armored offensive.
