An optimist, a pessimist, and an engineer walk into a bar. The bartender pours a glass of water and places it on the counter.
“Alright,” says the bartender, “what do you all see?”
The optimist immediately beams. “Oh, how wonderful! The glass is half full!”
The pessimist sighs dramatically, shaking their head. “Typical. The glass is clearly half empty. What a waste.”
The bartender looks at the engineer, expecting a similar philosophical take. The engineer meticulously examines the glass, pulls out a small notepad, and begins scribbling furiously. After a moment, he looks up, an exasperated expression on his face.
“You idiots!” the engineer exclaims. “The glass is twice as big as it needs to be!“
