ARE YOU A EXPERT TO HELP STUDENTS ON THEIR HOMEWORK LIKE ME?
Bob Pursley is actually more than "a expert." He has become one of the leading experts in homework help on the board. So much so that the "International Council on World Homework Online, Learning, Information, Knowledge, Education, Semantics, and Mental Enlightenment" (known as "IC WHO LIKES ME" for short) has bestowed upon Bob the indellible title of "AN EXPERT" rather than "A EXPERT."
Bob has worked so hard that the council decided he should be rewarded the right to have the extra "n" in the article preceeding his title.
Congratulations, Bob, on this great accomplishment.
Actually, kidding aside, Bob seems like a fantastic teacher. I wish I had him in some of my classes when I was in school.
