So Much Effort
Some people might think the guy on top of this truck is stupid, but he could also be a genius. Making others believe you’re working hard when you’re not could be clever, especially if they’re gullible enough to fall for it.
We believe he’s probably quite bright and merely feigned involvement to avoid the strenuous labor, but if he isn’t and genuinely thought he was assisting that truck move… maybe the power of imagination helped him.
