I got the joke though. I think. Well, it makes sense to me.

Hel- is the root meaning "sun," from "helios." Sink sounds like, well... sinking. And the "i" makes it sound Finnish? I dunno. Tell me how ridiculously wrong I am xD

Money is weird.

It certainly is. In Venezuela right now I'm told people are malnourished and it's really hard to get medicine because of the economy... and yet a couple of weeks ago I heard people were fueling up their cars for free, because the price of petrol is so low that with their redenominated currency there is literally no way to pay an amount that small.

Money is weird indeed.
