My first class of the day is filled with streetwise students. I'm always on them about "dropping the f bomb" and their "potty mouths".
On Friday, we were discussing upcoming finals and were reviewing various topics. I wanted them to stay on task, and was *jokingly* warning them not to bug me or we wouldn't get much done. In my mind I'm thinking "don't piss me off, ..." but I didn't want to say "piss", so I edited and said, " don't p. me off". ... Hmmmm, they all ewwwwed and said that that just sounded wrong.
