Question?

What's the difference between me and most of my friends?
a) I'm thinner than thin air
b) I'm thinner than thinner
c) I started a blog in 2008
d) All of the above

Hopefully your answer is not (d). Though it may be true, the intended answer is (c). Please do remember cos it may be tested in your exams.
