I know someone who subconsciously puts "like" in her English papers and such.
For example:
"It was, like, the best, like, book he ever, like, wrote."
I'm not kidding. She asked me to proofread her paper once and I almost threw it down on the ground. Incorrect grammar is a major pet peeve of mine...and THAT is just ridiculous.
