Nope. Engineer.
Pessimists think the glass is half-empty.
Optimists think the glass is half-full.
Engineers think the glass is twice as big as it should be.
Then there's the joke about a priest, a lawyer, and an engineer who faced execution by guillotine during the French Revolution.
As the priest mounted the platform, he said, "I am righteous and the Lord will save me." He took his position, the blade was released, and the blade stopped halfway down. The executioner explained that only one attempt at execution was allowed and the priest was set free.
Next the lawyer mounted the platform and said, "I am innocent and deserve to be exonerated." He took his position, the blade was released, and again the blade stopped halfway down. The executioner explained that only one attempt at execution was allowed and the lawyer was set free.
Finally, the engineer mounted the platform and said, "I see your problem right there. A screw in the frame has backed out and is interfering with the blade."
