Does anyone know where I can find the list of Blurnsball rules from Futurama? Do they exist? I hope to God they do!
All I know is that if you hit the blurnball into that small hole, all the hamsters get released and I spit my drink out my nose from laughing.
those are chinchillas and I laughed my ass off too 
“I’m starting to get the hang of this game. The blerns are loaded, it’s three blerns to two antiblerns and the infield blern rule is in effect, right?”
“Other than the word ‘blern,’ that was complete gibberish.”
In the commentary for “A Leela of Their Own,” the directors and writers comment that they did originally intend for lots of wacky rules and such, since we would just see passing glimpses of the game, but when an entire episode centered around it, it basically turned into baseball but with the ball on a string. 
There is no rulebook that I know of, but this wiki article should help a little.
