The funniest thing about that movie is that the night my wife and I rented it (in a fit of curiosity) we had our baby (a bit unexpectedly, no problems though).
So now my wife associates her labor period with watching the movie love muffin. That's something we'll tell our daughter when she asks us all about the time she was born.
By the way, my wife and I liked most of it (though it was stupid). Didn't care much for the sea cucumber part or the bottle-rocket-out-the-ass part. The floodgate was great, as was the hardware store/toilet part.
