What Happens: During a jeep chase through a Brazilian jungle, Indy’s newly-discovered son Mutt Williams gets tangled in some hanging vines but manages to keep pace by swinging through the foliage with a pack of friendly monkeys.

Why It's Stupid: Most obviously, because even a PCP-loaded Tarzan couldn’t keep up with a speeding car using vines and gravity. But most aggravatingly, because George Lucas’ clumsy CG fingerprints are all over the stupid monkeys and their stupidly stupid unreal smiling stupid faces.
