Forest, Grove
You have a tree and another tree. You basically have yourself a forest!
Follow the logic of this one and you should be okay.
りん
はやし
None
So, now you have this forest and you want to cut it down (so much money!). But, you don't have any tools, only your hands. You think... I've done karate for a while, so I can probably chop it down that way. You get in a chopping stance, then do your battle cry and hit: "HAYA ... .SHI******!" (はやし)
Obviously that didn't work well - you'll want to focus on your battle cry plus indecent swearing right afterwards to remember this reading.
