Akpos and the Science Teacher

A new science teacher walks into the classroom.

Akpos asks the new teacher "Excuse ma, if you mix Omo and Klin, will there be foam?"

Teacher responds "Yes of course, why ask such a silly question at the beginning of the year, are you going to pass this class at all?"

Akpos laughs and whispers to the other kids, "such a dumb teacher, how can you get foam without adding water, are we going to learn anything at all from this teacher?"
