An eagle-eyed passenger got a surprise when they looked out the window shortly after take-off at an airport in the US.
Can you spot the cheeky drawing carved into the dirt below?
The bemused passenger took a quick snap and posted the image to Imgur, where it has been viewed more than 255,000 times.
A few viewers were quick to spot something amiss with the photo, but most were left scratching their heads.
"I thought it was those houses spelling a word, but I couldn't make it out," said one viewer.
"I don't get it. Am I missing it?" said another.
