■PREVIOUS THREADS

See >>2 for links.

I stumbled upon a random sentence on the Internet, the lyrics of a song, and I thought maybe you guys would want to crack it.
来年のことを言うと鬼が笑うって言うなら笑いたいだけ 笑わせとけばいい.
The official translation is: "They say the ogres will laugh next year, I say let'em laugh all they want".
It's probably an alright one, maybe a bit too liberal, but I'm not at a level where I can say that comfortably.
Anyways, my questions:
来年のことを言う
Why the heck does that take を? As far as I know, that would literally mean: They say "next year". Unless it's the object particle for another verb, but the only other one is 笑う. It doesn't seem to make a lot of sense.
鬼が笑うって言
The use of って言 there would indicate that every time we use 笑う in the sentence, it takes as a subject 鬼, am I right?
笑わせとけばいい
This is just a clusterfuck of verbs and particles and I don't know what any of it means. As far as I know, 笑わせ is causative form  and ばいい means it would be fine if what it was said earlier happens, but about that とけ in the middle, I just don't know.
