Yeah, not sure why it missed it. But when prompted with the photo and "What's funny about this photo?" GPT-4 replied:
"The humor in this photo stems from the anticipation of an unfortunate event that seems likely to occur. A portable toilet is being transported on the back of a truck that appears to be entering a tunnel with a height limit, and a convertible car with its top down is closely following the truck. The implication is that if the portable toilet were to hit the tunnel entrance due to being too tall, its contents could potentially spill into the open convertible behind it, leading to a very messy and unpleasant situation. The text "WAIT FOR IT" plays on the tension of expecting something bad to happen, adding to the comedic effect."
