As Pope Francis travels home from his six-day tour of Washington, DC, New York, and Philadelphia he will take with him a fairly unusual memory.
The pontiff met a very little version of himself as he drove down the Benjamin Franklin Parkway to hundreds of jubilant fans.
The meeting, captured on a video shared by news channel 6ABC Action News, shows baby Quinn held into the air as Francis approached in the popemobile.
As the vehicle moves around the corner, the religious leader can be seen instantaneously smiling as he catches sight of the baby donned in full robes.
Security guards then picked up Quinn from the crowd and handed her over to Francis.
The Pontiff then kissed Quinn and whispered to one of his security guards.
As Quinn was handed back to his parents, the guard relayed the pope's message.
The child's father, Daniel Madden told local news: "He told his security guard to tell us that we have a great sense of humor."
Reactions to the video - which has been viewed on Facebook almost four million times - have varied, one user commenting: "I'm sorry that your parents dressed you in that ridiculous outfit."
Another more positive commenter wrote: "The Pope had a good hard laugh, enjoyed seeing the baby Pope, he has a good sense of humor and that's what he told the security guard to tell the parents that they had a good sense of humor."
And this user was just concerned: "I would of felt so unbelievably uncomfortable someone grabbing my baby and walking away to show someone."
