In the last few hours alone I have been inundated with examples of two of my biggest grammatical pet peeves. At the top of the list (no doubt a result of the date) is "wherefore".
Wherefore=why.
Juliet was asking why, of all the people she could dig, the dude she dug had to be a member of a rival family.
Second is the misuse of "myself" in lieu of "I" or "me", usually in the form of "Susie Creamcheese and myself went to the store". To know how you truly sound when you say that, give Susie the boot. You are left with, "Myself went to the store". The exception is when you have already used "I" or "me" earlier in the sentence. (e.g. I made myself sound like an idiot for using "myself" inproperly)
