Q: How did those trucks come out of tunnels that were painted onto mountains?
A: This one's easy. The Road Runner, being as intelligent as he is, would cover the opening of a tunnel with canvas, and paint it to look like a plain old rock, so when Wile painted it to look like a tunnel, it already was one!
Q: How did he survive those falls?
A: The studio used a stuntman and those airbag thingys to land on.
Q: How about the explosions?
A: All of those bombs were really just smoke bombs and lots of black powder. (We all know that the US Postal service would NEVER deliver TNT through the mail!)
Q: Who drew up all of Wile's blueprints and how come none of them ever worked?
A: The Army Corps of Engineers. That should say it all...
Q: Where exactly were all of those chase scenes filmed?
A: the Southwest American desert.
Q: How fast IS the Road Runner really?
A: He made it from New York City to Los Angeles in 2hrs. (get your slide rules out)
Q: What did Wile E. eat since he never caught the Road Runner?
A: Acme powdered chicken sandwiches(pat. pending) and Strawberry shakes.
Q: Where did Wile E. get the money to buy all that stuff from the ACME Corporation?
A: His 2nd uncle was Lassie
