which grammar error is worse?

B sounds more caveman like to me, so I have to go with that one as being worse.

B sounds a lot worse. I actually hear people say things like A all the time. not that that makes it any better

hmm..to me A sounds a lot worse.

they both make me want to shove needles in my urethra

To me "A" sounds worse because you can't tell whether the person left out the verb or didn't conjugate the verb properly (i.e. did he mean "my room needs cleaning?"

B sounds much worse. As Peggy said, that is just caveman-speak.
Surface, you flappy headed Canadians with your beady little eyes don't know what you are talking aboot.

B is much more ridiculous. If I heard someone say that I wouldn't be able to keep a straight face.

I'm going with B. They both make Shakespere cry though.

nah....A is worst...b is kinda worst

Maybe IT IS a Canadian thing cause B sounds everyday normal to me

Another Canadian vote for A being (much) worse.

To me, B sounds okay. Not *correct*, but nowhere near awful.

make that canada voting solid A...

B sounds like everyday, colloquial bad grammar. and i mean, technically it should be "i am finished (with) my book" or "i am finished (with) class," because 'done' isn't really the right word for those sentences. but people say "i'm done my book" all the effing time.

at least in canada, we do...

Ya same here....

I too am Canadian.

Huh. Well, I'm North of Canada right now. Does that count?

Wow. Sometimes my keen insights stun even me.

"i'm done my book" or "i'm done class" (missing 'with') is okay. Atleast when you're talking to your book or class...
Missing a comma in that case, but who cares about commas anyway?

which one? im from erie
maybe thats why i thought A sounded sort of normal.

A much worse!

I've heard A before. I think it's a common-ish coloquialism.

So don't blame me, I voted for B.

B

A is the common way of speaking in Pittsburgh though.

A is pretty common around here, too. B is just plain wrong. So B, i vote B.

now there's white-out all over my screen!
