Double Negative

In my work...part of my duties include writing reports and occassionally someone will criticize our method or our use of the English language and this usually ends up with us having to sit through another couple of hours listening to some “expert” speak on the proper and effective use of the English language.

As I did my best to stay awake as the linguistic professor was lecturing my mind was sorta drifting...

"Yeah...right"...I replied.
