What were you doing up the Amazon?

Looking for snakes. I'm an ophiologist.

I thought you were in the beer business.

Beer? Ale!

What's the difference?

Between beer and ale?

Yes.

My father'd burst a blood vessel if he heard you say that. There's a big difference. Ale's sort of fermented on the top or something, and beer's fermented on the bottom, or maybe it's the other way around. There's no similarity at all. You see, the trouble with being descended from a brewer, no matter how long ago he brewered, or whatever you call it, you're supposed to know all about something you don't give a hoot about.
