Who called it a Spanish teacher instead of an instruction Manuel?

Manuel runs into his old friend Pedro... and asks ""Pedro, where ya been?"" ""Ay amigo, I was at Yale"" ""Yale? How you got to Yale?"" ""I was laying on the beach"" ""You got into Yale for lay on the beach"" ""Si, but the beach was screaming""

What do you call a Spanish man who has just got out of hospital? Manuel...

Forgive me for this one A German soldier who loves animals can't decide what to do after WWII. His friend says, Otto, it's easy to figure out. You're a Veteran Aryan.
