I really enjoy deadheading roses (cutting off all the flowers that are dead or looking past their best to encourage more to take their place). Also mowing lawns, and clearing duckweed out of the pond. I never, ever thought I'd get into gardening in any way, but since moving back in with my parents (temporarily) and not having a job yet, it's been nice to take pride in keeping the garden looking tidy.
I also enjoy most of the (many, many) menial tasks involved in owning horses, be it mucking out fields and stables, filling haynets, checking their hooves, or anything else. It's nice to have to get out of the house a couple of times a day whatever the weather, and I love being around the animals too, even if I'm just scrubbing the algae out of a water bucket rather than actually riding.
EDIT: Oh, nearly forgot one of the best ones: routine computer maintenance stuff. I really enjoy cleaning up my family's laptops when they've been abused for a while, both literally (taking them apart and cleaning) and figuratively (installing updates, defragging, removing unnecessary stuff, diagnosing problems, etc etc). Similarly, I love tweaking a new computer/laptop to get all the settings and programmes just the way you like them. But then again, I also enjoy grinding in WoW, so I may just be a bit odd like that.
