I was watching the movie Full Metal Jacket the other day and there is this hilarious line (although a little rude...my apologies!) where the army drill sergeant tells a private: "I bet you could suck a golf ball through a garden hose." After hearing this, I began to wonder how this would be said in Spanish and I was wondering if someone could give me a hand. I want something that sounds colloquial and something that would sound as funny in Spanish as it does in English. Also, I was trying to think of a good way to express "I bet" in this case and I am sure there has to be a better translation than "yo apostaria"! Could you make sure to include a common way of saying something like "I bet"? Gracias de antemano!!
