SOLVED. Sci-fi book about an alien stand-up comedian [s]

[Izidrel]

I read this book 5 to 8 years ago. It was a library book so I'm not sure how old it was but it didn't look ancient. I think there was a picture of the earth on the cover, but I read the french translation, so the original cover might be different. By the way it was quite poorly edited and translated so I don't think it's a very well known book. I rememberthe title as "The world according to..." but ive had no luck finding it so i might be wrong. I think the author was male. It was a sci-fi book for adults.

A main character is an alien who has a stand up comedy show on TV or the radio. I think the title of the book is the title of his show. His shows start out very funny and he builds up quite a following but they become gradually more bleak as he gets more and more depressed. I think there's a thing about his plants dying, as well.

Other character include a male writer (i think hes a/ the protagonist and i think he helps the alien with the writing and promotion of his show) and a female hippie type, I think at some point they go together in nature and trip on magic mushrooms or a similar substance. They probably have sex together as well.

The antagonist is a homeless girl who gets into crack and somehow ends up with weird powers and also rats are involved.

(view spoiler)[The book ends on a big confrontation between the alien comedian and the crackhead ratgirl on which the fate of earth depends, somehow. (hide spoiler)]

I was probably not old enough to read this book but I remember finding the whole thing very weird, with strange similes and long parentheses about spirituality and Buddhism and drugs and probably other things.

Thank you!

The World According to Garp (idk, sounds alien enough to me just from the title) good luck

It's definitely not The World According to Garp which contains no aliens and is about the life of an author who is the son of an extreme feminist author.

[Izidrel]

Yeah, that's not it, unless I spectacularly misremember it. Thanks for trying !

He Walked Among Us maybe?

[Izidrel]

That's it! Thank you very much!!
