A guy is sitting in a bar... And in walks a friend he hasn't seen in a few weeks. Being curious as to where his buddy has been, he asks what's been going on. His friend replies ""after that last bender we had I figured it was time to lay off the sauce for a while"". The first guy asks ""what was so bad that you felt the need to cut back?"" Well, says the second guy, after we got hammered I went home and blew chunks."" That's nothing to be ashamed of says the first guy, we've all done it. The second guy gives a mournful shake of his head and says ""you don't understand, Chunks is my dog!""
