Grammatical rules you like to break
 

Think of this as the optimist's version of Batman976's post. :)

I like to verb words. For instance: I'm Tilting Forum Projecting instead of homeworking.

Well-crafted run-on sentences can be expressive as fuck; extra semicolons never hurt anybody.

Ain't is a word!

You like to look stupid?!

Well, my g/f does like when I dangle my participles, if you understand my meaning... heh. Hoo boy, am I tired.

I just like to piss smart people off. :p

Sometimes it's difficult to not end a sentence where the preposition is at!

"stoopid people do stooopid things
smart people outsmart eachother"

I, purposefully, never learned how to use, commas.

Haha... One of my friends used to always add the word "for" to the end of his "why" questions. We started doing it just to make fun of him and it sorta stuck.

"Why are you doing that for?"

Also "sorta," "kinda," "gotta," or any other similar words are in fact words.

I like to emulate Sal from Futurama, add "s" to words "Yous guys" etc. I also like the occasional extra "the" such as "This is the sucking."

I often despise the his or her rule.

Example:
If the doctor gives you medicine, you should follow his or her advice.

Just pick a gender!

Intentionally mispronouce words. Here's an example that really gets under the skin of one of my friends.

Nuclear

your/you're--as if i really care..

I like to always split my infinitives.

Reminds me of a quote from E.B. White to one of his friends:

"I've finally found a way to end a sentence with five prepositions. A boy is going to bed, and his father brings him a book from downstairs to read to him, but it's the wrong book.

"The boy says, 'What did you bring that book that I don't want to be read to out of up for?'.

"And how are you?"

Oh yeah, totally. Still, I think that it's hard to deny that English is gender-biased; there's no reason that "he" should be the default gender. So I usually alternate between "he" and "she" between paragraphs (assuming they're referring to different groups of people).

I use hyphens and dashes often - even when they are not needed.

Sometimes once I get started writing- that is, when I sit down in front of the computer (an altogether enjoyable experience, might I add)- I can go on these extremely long sentence runs in which very little or nothing at all happens except that the sheer number of words in it can baffle the mind; at other times, it seems as though my mind does this on purpose just to fuck with me and lead me to believe that one coherent thought can be expressed in one really long sentence when, in fact, it cannot, and I find, quite despite my best efforts, that the use of the comma, as handy as I find it, can become a hinderence to the writing process, as it causes me to use it, against my better judgement, too frequently.

I enjoy creating run-ons.

i use commas too much, usually where i would pause while talking and i pause a lot, for affect and all...
and i use ellipses a lot...
i try to write just like i talk, sometimes running together, so people that know me can almost hear what i'm saying

Lmao, crackpot.

Sometimes it improves practical communication when you "dumb down" your grammatical structure.

And it's just fun to start a word with a conjunction sometimes.

I take it then, that you tend not to use capitalization when speaking? :D

its vs it's --- I break that rule like crazy and I don't care.

I like to confuse stupid people. I like to suggest discussing what they think of Alternate Realities in the Fourth Dimension. I just like to see the confused look. Anything as abstract as a discussion like that confuses me when I haven't had much sleep. Some people don't even respond

My grammer problem is simply that my sentences are all to often verbose. That's the biggest problem that tend I continue. The one I'm trying to break is that I say "like" too often.
