Other mistake: When the bus starts to leave the Hoover dam (as seen through Dallas' binoculars), the driver is missing. The steering wheel is shown with no-one behind it.
Other mistake: When Beavis and Butthead start walking through the desert, their shadows don't match the direction in relation to the sun.
Plot hole: When Butthead pushes Beavis out of Muddy's car, Beavis causes a huge car crash. Then, a few seconds later Butthead falls out and causes cars behind him to crash, but the crash that Beavis started made a barrier along the highway, so how could those cars get behind Butthead so fast? (00:51:50)
Beavis: Hey, Butt-head, this book kicks ass. There's this talking snake, and a naked chick, and then this dude puts a leaf on his schlong.
Butt-head: Cool.
Trivia: Husband and wife, Muddy and Dallas Grimes, were voiced by Bruce Willis and Demi Moore, who at the time were married.
