20 bags of manure
Someone in Crawford Texas sent 20 bags of manure to the place where Michael Moore's movie was to be shown,

Overnight, 20 bags of composted cow manure were dumped near the spot where television crews do live broadcasts from Crawford, a few miles from Bush’s Central Texas ranch.
The fertilizer, in 25-pound bags, included a sign addressed: “To Michael Moore. One piece of Bull**** deserves another."

which apparently caused Moore to stay away, even when Moore had said he'd "bring the movie" to Crawford and had previously invited the President to see the movie.

Moore wasn't the only one missing: the NYTimes reports that "only a handful of moviegoers from the tiny hamlet of Crawford were in attendance. There appeared to be twice as many foreign exchange students from Belgium as locals."

As far as the manure goes, Crawford Police Officer Ken Jones is quoted as saying "I do appreciate the guy leaving (the manure) in the bags."

Here in The Principality a couple of years ago a woman was caught trying to steal at the Princeton Shopping Center when shoveling (unbagged) horse manure into her car trunk. Obviously Crawford is not a college town.
