Note back to school:
The teacher who wrote this sexually explicit biology test has type O blood.
A father who read it has type A blood
A mother who read it has type B blood
If the teacher is found knocked out on the floor with a busted lip and a broken nose, what mixture of blood types might be found in the blood splattered nearby, if both the father and mother both have bruised knuckles?
ROFLMAO!!!
PERFECT
