Yet it's hard to escape a little humor when studying a language like Yiddish, which is full of wit and playful turns of phrase. Discussing the icy weather, the students found an expression for "I'm freezing my butt off." There's also one that translates to "It's as warm as a corpse's hand." And the crowd favorite: "As long as God has been doing business with frost, He's never made a deal like this."
