Logic Puzzle

I get on the train today, and there’s two guys near the back of the carriage. At least one of them is clearly drunk, and they’re both big violent looking guys. They’re both getting kind of aggressive with each other.

They became a little harder to take seriously once I overheard a few snippets of their argument:

“Fuck you man! That works, I solved it!”
“You’re not fucking listening to me. You can’t do it that way, because the goat will eat the damn cabbage.”
“The fuck you talking about? The goat’s still on the first side of the river, I’m sending the fucking wolf over this time!”

I got off the next stop, so I didn’t find out if the guy managed to solve the puzzle, or if they ended up coming to blows over it…
