Exhausted



A gynecology student switched to car mechanics in his final year at college.
In his practical examination we was awarded 150%.
He questioned his professor as to how this could be. The prof said:
"For correctly dismantling the auto engine we gave you 50%.
For successfully reconstructing it we gave you 50%.
However, we awarded you a special bonus of a further 50%
for achieving all this through the muffler pipe."
