Dumbest grind ever?

What's the dumbest grind you've ever done?

I got a couple heads doing slayer so I decided to get the crawling hand and cockatrice since I don't get those assigned as tasks.. I just burned 3438 granite cannon balls killing moonlight cockatrice and got it at 1338 KC. I'm a very casual player and have no intention of clogging. I just felt like it. I got basically nothing of value out of that grind.
