Rush Limbaugh was uncharacteristically quiet today after Chelsea Clinton recounted how the conservative talk show host appeared to make fun her looks by comparing her to a dog when she was 13-years-old.

Secretary of State Hillary Clinton, however,  had harsh word for Limbaugh when reminded of  the incident saying, "We're better than that."

Chelsea Clinton spoke last week about Limbaugh's comments while on a panel about women involved in politics. The former first daughter made the comments while defending Georgetown University student Sandra Fluke who had been ridiculed last month by Limbaugh as a "slut" and a "prostitute" for testifying before Congress in support of a government mandate requiring health insurance to cover contraception.

"She and I actually have something in common," Chelsea Clinton said.  "We've both have been attacked by Rush Limbaugh."

"She was 30. I was 13," she added.

When her dad, former President Bill Clinton, was in the White House and Limbaugh was on television as well as radio, the conservative commentator had this to say about the teenage girl living at 1600 Pennsylvania Ave. back in 1993:

"Socks is the White House cat. But did you know there is also a White House dog?" Limbaugh said on his television show before showing an image of the young Clinton.

"Thankfully I had grown up in public life and knew that having thick skin was a survival skill," Chelsea Clinton said after recounting the incident. "I do also believe if you have the right type of enemies you're doing something correct."

Her mother today had tough words for Limbaugh without mentioning his name.

"I think we need to call people out when they go over the line," Secretary Clinton told MSNBC.  "They're entitled to their opinion, but no one is entitled to engage in that kind of, you know, verbal assault."

Limbaugh did not mention either Clintons' remarks on his show today nor did he return ABC News' request for comment.

He caused a furor when he  made his comments about Fluke, prompting some high profile advertisers to pull their ads from his show.
