this rank among my most favorite of ernest movie . the bumbling janitor ernest p. worrel ( jim varney ) and his wishy washy and history professor friend and abner melon ( ron james ) and stumble upon an old revolutionary war cannon know a goliath and that abner have be search for his whole life . unbeknownst to them and other people be also interested in the cannon because it contain the crown jewel of england represent a history professor and abner bos and who moonlight a a crime bos and and an british secret agent who want to recover the jewel for england . a the other reviewer state and ernest ride again be a bit more serious in plot and but it be fill with laugh nevertheless and especially in the scene where varney play against straight man ron james . don not miss the hilarious canon chase scene . the relative seriousness of the plot make the laugh that much funny . definitely a must see and especially for those who have never see an ernest movie .
