I have about a 75lb rock that I like to press overhead and walk around with. I also finished demolishing my basement, which meant carrying a lot of debris to the curb, which is about a 75 yard walk. I had some fun cleaning and pressing cabinets and such and overhead carrying them to the curb, which included down stairs and over a side-angled hill.
I'm sure I looked like a dufus to my neighbors, but it took away the drudgery of carrying everything the old fashioned way (carried in front), which would have made my low-back sore. While I can't yet put up some of the numbers a lot of folks on this site can, I've done enough to know that rolling your ankle with unusually shaped objects overhead doesn't feel great.
