Oh, Really?

A post by Steve Sailer on Barack Obama's first book evoked nostalgia for the old "O'Reilly" jokes:

"I heard she's marrying an Irishman."
"Oh, really?"
"No, O'Reilly."

"Her husband bought her a fur coat."
"Oh, really?"
"No, opossum."

So I came up with this knee-slapper:

"JFK and Reagan were Irish. I think we need another Irishman in the White House."
"Oh, really?"
"No, Obama."

Ta-da-dah.
