I'll raise you a 114lb/52Kg battery (not USPS, though; FedEx, IIRC):

I, too, felt bad for the guy until I saw him toss it on his shoulder like it was nothing, carried to the garage and gently set it down. Not a big guy, either. :-)

The UPS person who delivered my full size punching bag was not super thrilled. 100 lbs and 150cm tall odd shape. I wish I was there when delivery happened as I was prepared to tip them for the inconvenience.

My dad made a black walnut coffee/end table for me, and instead of waiting for the next time he drove out here, he decided to ship it via FedEx. It was like 100 lbs, but due to the very large size and somewhat wonky shape, he then built a plywood encasement for it with some used carpet to keep the epoxied table from getting scratched. It was quite a sight to behold. The FedEx guy had no problem hauling 100+ lbs of large, awkward object, but he was curious as can be as to what on earth he was delivering.
