A man walked into a beer store and got a case of Keystone.
He walked into the same store 1 week later.
He asked for a case of budwiser.
The man working the counter said "you didn't like the keystone".
The man said "no it made me blow chunks".
Then the man at the counter said "well that happens to all of us".
The man said "no, you don't understand, Chunks is my dog".
