Even shock jock Howard Stern is shocked by Donald Trump's "locker room talk" -- now that's really saying something!

During his SiriusXM radio show on Monday, Stern, who has had Trump on his show on several occasions, talked to sidekick Robin Quivers about Trump's “locker room talk" claims, following the recent scandal involving leaked tapes in which the Republican presidential candidate can be overheard making lewd comments to Billy Bush, using the now-infamous phrase: "grab them by the p-ssy."

Stern, who is known for his own devious behavior and talk, had a number of things to say on his show about Trump's assertion that his inappropriate comments about women were mere "locker room talk" -- and nothing more.

“A lot of the show that I’ve been doing for my entire life, radio show publicly, is an effort to sort of do ‘locker room talk,’ to express all kinds of s--t and just not even care what anyone thinks,” said Stern.

The 62-year-old continued, “But this idea of ‘locker room talk’ … all the times I’ve been around guys — and believe me when I’m around guys 85 percent of the times you’re talking about p--sy — but I have never been in the room when someone has said, ‘Grab them by the p-ssy.’”

The radio host added, “No one’s ever advocated going that step where you get a little bit, ‘Hey, I’m going to invade someone’s space … A lot of [locker room banter is] real kind of desperate talk. The reason it’s in a locker room is because no one’s proud of it.”

Let's get real -- if Howard Stern thinks you've gone too far, then you've really gone too far!

While Stern was quick to slam Trump's comments, he also said he won't replay old tapes from the businessman's past appearances because he doesn't want to “f--k someone over.”

Oh come on, Howie!
