The clip Raiding the fake town from Blazing Saddles (1974)
Well, they're through the tollbooth.
Look at this, they're buying it!
All right, here we go. Hold your ears, folks!
It's show time!
What are we going to do?
Any minute now they're going to discover the town is fake and pull out!
You think you could squeeze off a little shot from here...
...and set off the dynamite down there?
I'll give it a try.
Oh, Lord, keep this man's eye keen...
...and may God grant...
It's a fake!
We've been suckered in!
Okay, folks, let's wipe them out!
