On Monday, shirtless photos of Elon Musk started floating around the Internet.

He had been photographed shirtless in a yacht in Mykonos, Greece.

Many users took to weigh in on the shirtless snaps and poke fun at his complexion.

“Good god man, he can afford a spray tan. Fish belly white,” one user commented.

“Is he covered in sunscreen?! Or is that him?” another user asked.

Several users made references to Casper the Friendly Ghost.

Even Elon Musk took the time to comment on a shirtless photo of himself.

“Haha d---, maybe I should take off my shirt more often … free the nip!!” he tweeted.

He then added, “(already back in the factory btw).”
