“I was so drunk last night, when I got home I blew Chunks” sounds like a harmless expression—until the second line of the joke explains, “Chunks is my dog!” The joke was posted on the newsgroup rec.humor on April 10, 1995, and has been printed on several images.

Heard this one on WDVE Pittsburgh:
 
“Oh god I got really drunk last night…”
“That’s OK buddy, everybody was ripped, not just you.”
“Yeah, but I got so drunk I blew chunks…”
“Oh that’s nothing bad, everybody got sick last night.”
“Man you don’t understand. Chunks is my dog!”

Every night of his adult life, a man went into a bar and ordered a shot of gin.  One night, however, he came in and asked the bartender for a glass of orange juice.  Well… the bar tender asked the obvious question: “Why are you, all of a sudden, ordering juice instead of gin?” “You see,” answered the man, “last night I got so drunk that I came home and blew chunks…”  “No worries,” said the bartender, “it happens to all of us once in a while…”  “No,” grimly replied the man, “you don’t understand - Chunks is my dog!”

Three guys were discussing how drunk they got the night before. The first one says “I was so drunk, I blew chunks all night!”
The second one says, “I was so drunk I passed out in an alley!”
The third one says “That’s nothing, I got so drunk I brought home this dame I didn’t even know and had sex with her. Then my wife walked in!”
The first guy says, “Uh…I don’t think you two understood how drunk I was… Chunks is my dog.”

Blowing chunks
submitted February 20, 2013 by Jakon
At work, three friends get into an argument over who got more wasted the night before.
“I got so drunk last night, when I got home I blew chunks,” said the first man.
“I got so drunk last night, I had to sleep outside because I couldn’t make it inside my house,” said the second man.
But the third man was certain he got more wasted than his friends. “I got so drunk, I set my entire house on fire!” he argued.
“I don’t think you guys understand,” said the first man. “My dog’s name is chunks.”
