A little bit about my job

From the “Things that may only be amusing to Tony” file:

Today in class, the students had to practice making sentences into questions, the one that amused me was this:

Ken’s pen is on the desk.

So, in question form:

Is Ken’s pen on the desk?

The problem was at least half a dozen students wrote this:

Is Ken’s pen is on the desk.

The problem is that some of the students didn’t put a space between the third and fourth word of the sentence.

Hilarity ensued.
