There was a football coach that had a player on his team that was a bit
slow.
The Dean told him that if the player could learn the formula for water,
then
he would be allowed to play in the big game. 

The day of the big game came and the Dean called the player into his
office
and asked him to recite the formula for water. The player grinned real big
and said, "H I J K L M N O."
