Obama sandwich selfie?

President Obama squeezed in for a "selfie sandwich" with science aficionados Bill Nye and Neil deGrasse Tyson at The White House Friday.

Tyson, an astrophysicist, tweeted the photo of the threesome attending the inaugural White House Film Festival for students.

Between screenings, "the science guy" Nye Instagrammed it with the caption, "What an honor. And we even pulled off "The Presidential Selfie" (!!)"

Obama stirred Twitter in December for taking a "selfie" at Nelson Mandela's memorial service with British Prime Minister David Cameron and Danish Prime Minister Helle Thorning-Schmidt.

The image of the world leaders’ snapshot ignited a flash of social media reactions, inspiring the hashtag #selfiesatfunerals on Twitter.
