Saloon Old-Timer #1: Take a look and see what just breezed in the door.
Saloon Old-Timer #2: Why, I didn't know the circus was in town.
Saloon Old Timer #3: Musta got that shirt off'n a dead Chinee.
Bartender: What'll it be, stranger?
Marty McFly: Uh, I'll have an... ice water.
[the old-timers laugh]
Saloon Old Timer #3: Ice water?
Bartender: Water? You want water, you better go dunk ya head in the horse trough out there.

Bartender: In here, we pour whiskey.
