'No Way, Man!' Seth Rogen REFUSED to Take a Picture With a Very Prominent Republican

The comedic actor recalled the incident while chatting with Stephen Colbert on "The Late Show" on Friday.

Rogen explained how he attended an event hosted by former presidential candidate Mitt Romney for a brain health summit. (The actor is an advocate for Alzheimer's research.)

"I went there and almost all the attendees were Republican people," Rogen began. "And I'm okay with that, but I didn't know how I would react, honestly, in every situation."

He then explained how two "very nice" young men approached him and asked him to take a photo with them. "Then they said, 'Our dad wants to meet you,' and I turned around and Paul Ryan was walking towards me," Rogen said.

"How'd that go?" the CBS star asked, to which Rogen replied. "Well, my whole body puckered, I tensed up, and I didn't know what to do," The "Preacher" creator said that Ryan proceeded to shake his hand and ask for a photo.

"And I said, 'No way man!'" Rogen recalled, as the audience started laughing.

"And I couldn't stop," he continued. "And I said, 'Furthermore, I hate what you're doing to the country at this moment and I count the days till you no longer have one iota of the power that you currently have.' And I look over and his kids are still standing right there."

The actor said that he felt "conflicted" because it's not the kids' fault that their dad was Paul Ryan.

"I'm glad I didn't take a picture with Paul Ryan," Rogen added. "My hand -- I touched him -- so I don't know how I feel about that."
