Canadian Beer

A guy walks into a liquor store and says to the guy behind the counter: Give me a case of beer, but none of that Canadian stuff. The guy behind the counter says: What's wrong with Canadian beer? I'm Canadian. The customer says: Well, last night I drank a case of Canadian beer and I was blowing chunks. The guy behind the counter laughs and says: What do you expect, you drank a case of beer. The customer says: No, you don't understand, chunks is my dog.
