Bill and Ted's Excellent Adventure

Before "Beavis and Butt-head", before "Wayne and Garth", there was "Bill and Ted." They may be heavy-metal idiots who are flunking history, but Bill and Ted really grasp all of the time-travel concepts pretty quickly. Deep down, it’s actually pretty corny and innocent, and portends to teach kids about historical figures. But it’s most funny when the dudes finally figure out that time is on their side, and they use the booth to their advantage.
