Wikipedia: The comma ( , ) is a punctuation mark. It has the same shape as an apostrophe or single closing quotation mark in many typefaces, but it differs from them in being placed on the baseline of the text. Some typefaces render it as a small line, slightly curved or straight, or with the appearance of a small filled-in number 9.
Urbandictionary: Comma- a very important grammar thang. without it, many sentances would be very different.
Examples:
with comma: I helped my uncle, jack, off his horse.
with comma: I helped my uncle, jack, off his horse.
without comma: I helped my uncle jack off his horse.
The comma is my favorite punctuation mark, I use it far too often and most usually in the grammatically incorrect place. But I don't care, a comma represents a pause. Am I not allowed to insert a pause where I please? I ,(pause)like turtles.
Looking back I was never very good at correct punctuations or grammar anyways... is it extremely necessary to know what an adverb, verb(it's what you do, thanks TV!), prounoun, adjective, etc..the logical solution to this problem, which Im sure is a global epedemic, is to have more commercials.. those Verb, its what you do commercials were genius. Bring back school house rock, make more commercials. Help kids learn.
We like commas.
