 The movie is a _Jaws (1975)_ (qv) parody and many lines are direct  references: "Thats the thing about trees... theyre silent like the  night! They dont make a noise... they just stand there." "Everyone  out of the woods!" "This was no lawnmower accident!" "We tell them  theres a killer tree on the loose, and youve got pandemonium on  Memorial Day!" "Jim, if you open up those campgrounds on Memorial  Day, well, its like opening up a buffet, for chrissakes!"  "Apparently, a great white pine has staked its claim to the woods  around Hazelville." "A cage wont work with that tree!" "Didnt they  say on TV they caught the tree?" "Youre gonna need a bigger axe."
