I found Danger Slater's Love Me and Eirik Gumeny's Exponential Apocalypse both hilarious, and Screw the Universe is every bit as good.
The authors say they're glad the creators of Futurama didn't sue. It does have some overlap with that excellent TV show--a group of misfits bumble around space and shenanigans ensue--but Futurama never got one tenth this weird. I wasn't even sure what exactly was happening half the time, but that didn't matter because of the absurdist humor and constant stream of dick jokes.
This is chaotic, gory, sex-filled sci-fi bizarro that moves at the speed of, you know, something fast. I burned through it on the last couple of hours of an excruciatingly long flight--I don't think there's any better way to spend your 99 cents.
