First time I've seen a toilet with a thing thing!

What was that movie i saw once?..... there was a guy sitting on a toilet (lid down) to stop an alien critter getting out and he wanted to reach for his matchstick, to put in his mouth (he was an idiot) and every time he leans forward to reach it, the creature nearly gets out, but the guy is amazingly stupid and keeps reaching until the creature gets out and kills him

Yeah,it's a rare thing.

Dreamcatcher (2003)

Yes lol.
Quite a weird movie with weird alien leeches

Yup. A guilty pleasure, very guilty very pleasure. To me it feels like a self-parody of Stephen King (all his tropes are concentrated in it, even moreso in the novel). But heck, it's got snow, and aliens, and that weird scene where the alien-possessed guy on the snowmobile suddenly turns his head to smile at the camera... I still don't know how intentionally wile e. coyote that is, but it cracks me up every time.

Love that movie.
