I LOVE this movie. But that doesn't keep it from being one of the stupidest things ever made.

After you sit through what very well may be the worst opening score for any movie ever, ("Killer KLOWWOWWOWWOWOOONS, From Outer Spayhayce...") it cuts to Officer Mooney, which is the eternally pissed off cop that all sci-fi movies need, driving in a car, and cursing a young Christopher Titus (in his first acting role). Then the movie cuts to Mike and Debbie (the protagonists) pretending to make out in an inflatable raft in Mike's trunk.

A comet hits earth, Blob-style, in a forest. After some old dude overacts the fact that he is quite surprised, he looks for the comet, finds a circus tent, electrocutes himself, and is shot by a Klown. Then, to clarify the point that Officer Mooney is a bad man, he yells at two college kids for being law-abiding citizens. (How dare they?) Some other stuff happens, including Debbie and Mike running away from a popcorn gun (the most expensive prop in the movie) and a balloon dog. Thus begins a truly terrible movie. Some highlights:

- Klowns take over the drug store. This is probably the funniest scene in the movie. Two Klowns disguised as an animatronic gorilla and an animatronic clown (how original!) walk into the store, and trash it with facial powder and shaving cream. They turn the store owner into cotton candy, which they keep to eat later.

- The Terenzi Brothers. Words can not do justice to these two idiots.

- The "Psycho" Scene. This part is pure hilarity. Debbie strips, gets in the shower, and spends most of the movie in there without even coming out pruney. Popcorn crawls on the floor, stuff happens, Debbie steps out, puts on a robe, and gets attacked by clown-head puppet tube things. Debbie seems to realize that these things are harmless (one bites her shoulder, and its teeth bend, not hurting her at all), so she takes her sweet time shutting up their annoying chomping sounds. She runs around her house, seeing Klowns everywhere, and finally is put in a balloon and driven away.

- The Funhouse. A clown car drives up to a fun house. The good old clowns-pouring-out-of-a-car gag happens. The security guard tells them to leave, but the Klowns pull out pies. The guard asks, "What are you going to do with those pies, boys?" Obviously, they throw them at the guard, and the guard melts. The Klowns walk into the funhouse, with the midget klown pausing to put an engorged cherry on top of the pile of pies and bones.
