A student was working on a typing program first hour. The program gave a pictogram and the student had to decipher it, then type the solution into the appropriate boxes. She was stuck:
"Hey, Mrs. Spatula... do you know what this is?"
I look over. I see a "DO", an arrow pointing to a knot, a hand with the five numbered fingers, a "Y", an arrow pointing to an oar in the water, and two obviously male chickens.
I started to think out loud. "Do.... not.... finger? Your...."
Internal dialogue: OH MY GOD. THAT CANNOT SAY WHAT I AM ABOUT TO SAY OUT LOUD TO A STUDENT!!!
Thankfully, she figured it out before I continued with my thought. It was "Do not count your chickens", not "Do not finger your cocks".
