Oh!
I didn't do this, personally, but I saw someone that would send their villagers shovels and stuff and tell them to dig their own graves. It was genius.
Also, I torture Ken with fruit furniture by having a room full of fruit furniture. The same dialog pops up- "blah blah functional piece of furniture blah blah you can eat it! you mean it's not edible? wahh tricked again"
I like dat psychological torture. It's what gets me out of bed in the morning. And because Ken's a smug, he takes rejection pretty harshly. That's a nice thing, too. But he loves the ground I walk on, so. No hard feelings.
