UbiquitousBubbaI used to have a good grammar. Sometimes, people asked me if I had a great grammar. I'd just say, "Well, I think so, but I don't like to brag. Besides, I wouldn't want her to start gettin' all uppity."
sharkeI'm shocked at how many people are substituting "of" for "have" these days, e.g. "I shouldn't of done that."
