Back in the eighties, cowboys roamed the earth and made out with each other. And I mean proper cowboys. From the 1800s. The cowboys would say "isn't this the 80s?" And you'd say "yeah...the 1980s" And they'd get so overwhelmed they'd kiss.
The cowboys loved to go to the aquarium and say "SEA cows? now i've heard everything!"
Sometimes the cowboys would come by and just steal a cow. if you tried to argue with them, they'd say that cow came from the 1800s. "Look how primitive it is," they'd tell you. "Not like your Earth cows."
