Top two weirdest. First is a...tragic...romance. Featuring necrophilia. Second is a guy summoning a demon and various demons explaining (often with music) who and what his girlfriend who left him was. Entire movie, main character is sitting in a protective circle, while the demon Lo is usually positioned in front of him, as its legs were crushed (huge twist at the end).
And on some other stuff: I said "no non-obvious", aka "obvious". And yes, it was the innuendo I found amusing.
