Reminds me of the heartburn commercials when the offending food beats up the person that ate it (tums?)
Literally had that happen to me one time Was pulling a trailer behind the ATV one time and the trailer was a little wider than the bike. The bike easily passed by a 2" diameter maple but the trailer didn't clear it. The tree got caught under the front corner of the trailer which quickly bent it. The top smacked me on the top of the head and damm near knocked me out. Had no idea what had hit me.
