Overheard at school

After the announcements said that the cross country team was going to Appalachian State University for a meet:

I didn't know Appalachian became a state.  When did this happen?

To which another student replied:

Oh, I heard it on the news like last summer.

And, when discussing diatomic molecules (molecules made up of two atoms, di-atomic):

I wonder why we never hear of a monabolic plan.  Does that mean a diabolic plan is like plan B?

Oh how I want a dictionary and encyclopedia set in the room!
