Get a Life: Camping 2000 (1991)

After some pestering, Fred (Bob Elliott) reluctantly agrees to take his son, Chris (Chris Elliott), on his annual weekend camping trip. Chris brings along his friend Larry (Sam Robards), and neither one of them knows the first thing about the woods. The two annoy Fred so much that he ditches them, leaving them to fend for themselves. Before long, they grow hungry. Larry has only brought an assortment of sweaters with him. Chris' backpack contains a woman's shoe, shoe polish, his collection of desert island 45s, an extension cord, and three staplers. Luckily, he's also brought along his "lucky can of soup," but the two have no way to open it. In desperation, Chris turns to eating dirt ("kinda tastes like chicken") and sticks. When they find a berry bush, they think it's their salvation, but if they could only see Fred's survival book, they'd know these berries cause "paranoia and homicidal delusions." Meanwhile, Fred, enjoying his solitary fishing trip, finally grows concerned enough about the two idiots to go looking for them. But by this point, the berries have had their effect on Chris and Larry, and when they spot Fred, Chris initially thinks he's his "giant talking pet hamster," President Roosevelt. When they realize it's Chris' dad, they think Fred is hunting them. "That's why he's been fattening me up all these years," Chris reasons, "I'm his ultimate trophy." The two decide they have to strike first. ~ Josh Ralske, Rovi
