In the top photo, Joe Edd New is explaining to Johnny Holmes (not pictured) how close he (Joe Edd, not Johnny) came to passing calculus.  Linda Leason New is smiling because she's heard it all before.  You'll have to figure out who's at the back table on your own.

Next: Joe Edd, Claudia Moss New, and Linda.

Bottom: Ann Pendleton and Betty Boyd Storms. It's not easy to get a picture of Ann when she's not talking, but I managed it.
