In his segment Monday evening about the ongoing Secret Service prostitution scandal in Colombia, Daily Show host Jon Stewart focused on David Chaney, the agent forced into early retirement over his posting of a photo of Sarah Palin with a sexist comment while serving on her security detail.

Stewart took a keen interest in observing Chaney’s comment on the former Alaska governor, saying, “I was really checking her out, if you know what I mean?”

“Okay, first of all, we’re not really confused about what you mean, as to checking her out,” Stewart said. “You’re checking her out, ‘If you know what I mean’ is kind of a single entendre. Nobody here thinks she’s a library book and we’re confused.”

“Second, how the fuck does the Secret Service guy have a Facebook page where he posts pictures of himself guarding political figures? ‘Hey, check it out, it’s me, as the single trail agent on the standard V-line protection formation. The only vulnerability is from the right flank, if you know what I mean.'”

Stewart added: “What, are Secret Service guys on Foursquare too? Hey, just checking in, at the president’s previously undisclosed location, if you know what I mean.”
