A guy walks into a liquor store, and says, "Give me a case of beer, but   
none of that Canadian Beer!"

The guy behind the counter states, "Why what is wrong with CANADIAN Beer?   
 I am CANADIAN!"

"Well", the customer says - "I drank a case of Canadian Beer last night,   
 and I was up all night blowing Chunks!"

"Goodness!", says the guy behind the counter - "Drinking a case of any   
 beer would do that to a person!"

"Oh, No!  You don't understand - CHUNKS is my Dog!"
