Without cheating with Google Translate, I'm guessing about 10 ounces of re-branded 'Alpo'?
My dad always had a can similar to this in his office on campus. When people would say "duh, it's dog food" he would reply "well then by that logic, what is in a jar with the Gerber Baby on it?". Keep that can - it's a great way to break in freshmen.
This can totally cracked me up. I should probably retake the shot with three cans: "Ham", "Beans" and then "Dog".
