In the wake of Donald Trump's comments criticizing John McCain for being a prisoner of warin Vietnam, Jon Stewart is asking the question so many Americans are thinking: "What the f--- is wrong with him?!"

In a segment on Monday's Daily Show - the first new episode after a two-week hiatus - Stewart eviscerated the 2016 Republican presidential candidate and his supporters.

"The only reason you like this guy in the first place is because of the terrible things he was willing to say about Obama," Stewart said, referring to Trump's insistent refrain that President Obama release his long-form birth certificate. "But Trump has no control over the projectile vomit of dickishness that comes out of his mouth every time he opens it."

Mocking Trump's offensive remarks about McCain and other POWs, Stewart said: "And f--- cancer survivors too. ... I like people who don't get cancer."

Nonetheless, Stewart definitely doesn't want Trump to drop out of the presidential race just yet. After all, he's still got three weeks left as host of The Daily Show. "I so love this man," Stewart said, snickering. "I really feel like he's some sort of Jewish holiday waiting to happen."
