Mr. Keast caught you chewing gum in algebra class, told you to spit it out into his hand (you did), then rubbed it into your hair. 
I loved that guy!
He is a favorite of mine too Rem
Spent some PM time in our Wilson jr hi Store on a stool  in a dunce hat  watching him sell pencils  & erasers
Found him & principal Gladys Edwards making out in Arcadia park  sunny day  sweet looks
It was algebra  had me lay on the floor w a waste basket on my stomach  while you guys thru trash in
Had me stand  hold my nose against the chalk board  in his drawn circle  6" above my nose  No Erasing
Finally someone w a sense of humor & teaching
Thanks  Bill
