What is your least favorite chore?

Since we're all adulting now (at least I hope we all are), what chore do you hate the most?

I personally hate ironing... It's tedious, I hate standing in one spot, and it's easy to screw up. My s.i.L. and wife I've never seen iron once! Is that a woman thing? If I ever not ironed, I'd look homeless.

Honorable mention is changing kitty litter, I've tried some of the machines that auto-scoop and stuff, it doesn't really get much less annoying.
