Because the holiday name is in hebrew, not english, as such the "spelling" in english is strictly pheonetical. Hannukah, hanukka, chanukah. All technically correct. I'm jewish, its how you say it, not how you spell it.
Now, now, dear. That's a horrible way to look at it. Spelling is very important. For example, I called you an animal in the first sentence, and you didn't even know it because I spelled it wrong.
To keep the awkward animal eating going....my grandma likes to eat squirrel brains, and you need 6-7 to make a meal...
"Squirrel brains sound tasty. I know Ridley enjoys calf's brains, and I personally enjoy the brains of Armiistaan Mundaa'caws."
"Ridley grew bored with this thread weeks ago. I don't think he even realizes that I'm still posting in it."
"That is not going to happen. My own existence is linked to this thread. I intend to keep it alive for as long as possible."
"You dare challenge Allysana Vex'ori Graa Armiista?! I have conquered entire star systems! I have made armies of millions flee in terror at the mere mention of my name! I command the Matriarch, the most powerful starship in the known universe! You, dear girl, do not stand a snowflake's chance in Hell of defeating me."
Let me just... Hang on. *squeezes in between you two* I think... Hang on, this is tough. Excuse me. *pushes you two apart* Now if I could interject... I think this would best be settled with medieval weaponry. I suggest the flail or mace.
