Amos, jist last night we was at the store and I saw a whole bunch of people who was buying things right and left. They was snatchin' up them Xratedboxes and Tinkle Me Elmos and Nicotinepatch Dolls and all, yanking them off the shelves so fast they was leaving scorch marks.

Use of the subjunctive, like the use of the pluperfect, is often dependent upon what impression the author wishes to achieve. Now, I can easily compose grammatically correct sentences -- even entire paragraphs! -- but do not always choose to do so. Even a compound-complex sentence is not beyond me. After all, I have graduate work in ENGLISH!!! (Literature, I'll admit, but we were required be able to differentiate between a noun and a verb or they wouldn't permit us to take even our Bachelor's degree.)
