Also, here's something I wrote about him last year:
I know him best from a movie called The Sheepman, because it was a movie that my dad saw as a young man, and years after he'd forgotten the name of the film, he always remembered Gonzales-Gonzales's big line: seeing a shipment of sheep being brought in, he cries out: "The sheep has come in!" Dad said this got a huge laugh in the theatre. One afternoon we were watching TV and we noticed Gonzales-Gonzales in some kind of sheep-herding situation; Dad realized this was it, and we waited for the big line. When we heard it, it was like we'd finally recovered the lost gold or something. So thanks, Pedro.
