The black grandson pictured in former Gov. Mitt Romney's family Christmas photo was the focus of attention to MSNBC host Melissa Harris-Perry's conclusion to the "What's So Funny About 2013?" segment on Sunday, the Wire reported.

Drawing a chorus of laughter, the chuckles were directed at baby Kieran, who was adopted by Romney's son Ben and his wife Andelynne in September.

"One of these things is not like the others, one of these things just isn't the same," panelist Pia Glenn offered as a caption for the photo, which the Romneys' tweeted on Christmas Eve. (Lyrics of the original Sesame Street song are, "One of these things just doesn't belong.")

"And that little baby, front and center, would be the one," Glenn said.

Comedian Dean Obeidallah joked that the baby is a token.

"It really sums up the diversity of the Republican party and the RNC, where they have the whole convention and they find the one black person," he said.

MSNBC and the panelists were heavily criticized for the segment by conservative blogs on Monday.

"He's not a child adopted by loving parents prepared to provide him with a better life in keeping with the family's values," commentator Caleb Howe wrote tongue-in-cheek on The Right Scoop. "Nope. He's just a token. A punch line, not a person.

"It's funny because Romney is white and his grandson isn't, which is obviously hilarious. Because as everyone knows, the races should not mix," Howe added.

According to the Wire, Republican Sen. John McCain, who ran for president in 2008, also has an adopted child of a different race. McCain's wife Cindy adopted daughter Bridget after a cyclone relief trip to Bangladesh in 1991.

Glenn acknowledged the controversy on Twitter but fell short of apologizing, instead blaming the producers of the show for springing the photo on her and the panelists.

"Really? You think I'm a producer on the show? You think I chose that photo & new [sic] it was coming?," she wrote on Monday. "Yes, I sang the song. There are many children in the pic & only 1 black child. I don't see that as mocking or attacking the baby."

Harris-Perry and other panelists have thus far remained mum, the Wire reported.

Ironically, the segment ends by teasing the next block, an annual "'Look Back in Laughter' tradition of asking 'Hey - Was That Racist?'"
