I think the only thing I really hate doing is cleaning the shower. At our old house we didn't have the best water softener so our shower would turn a bit orange. At the new house we don't yet have a softener at all (we are getting one, just don't have one yet) and our shower gets quite orange (much more than the old house). The orange combined with the hair...I hate cleaning it.

My favorite chore is probably doing laundry, though it wasn't always. I don't mind washing dishes, vacuuming, dusting, cleaning the toilets, cleaning cages, yard work, or most anything else.
