Old joke;
A guy goes into a bar, sits down and asks the bartender what kinds of beer they serve.
"We serve Bud and Coors."
"Ok give me a Coors." Over the next hour he downs 30 beers and crawls out of the bar.
The next night the guy comes in absolutely wrecked. Through tired bleary eyes he asks the bartender what beers they carry.
"I told ya last night," the bartender said annoyed, "we have Bud and Coors"
"What was I drinking last night?"
"Coors but why do you care?"
"Well, well, ummm last night when I got home I blew chunks."
The bartender starts laughing really hard. "You moron no matter how many beers you drink you're gonna get sick. Brands got nothing to with it."
"No man, no wait. You don't understand. Chunks is the name of my dog."
