David Letterman just couldn’t resist giving Harrison Ford a cursory physical exam on the ‘Late Show’ Thursday night.

As Ford casually pointed out a scar he got after falling off a horse, Letterman grabbed his face, drew his head close and peered intently at his scalp for several moments.

“I don’t know. I can’t see it. I’m sorry,” Letterman said.

Ford looked somewhat bewildered afterward, but gave Letterman the opportunity to go further if he wished. “I’m circumcised also,” he said.

“Alright, well, let’s take a look!” said Letterman.
