What bond of friendship could Macaulay Culkin, Bob Saget and Seth Green possibly share?

Your guess is as good as ours but the unlikely trio, accompanied by Green’s girlfriend, actress Clare Grant, appeared to be having a wonderful time hanging out together in New York City last night. Check out the pictorial evidence, courtesy of Saget’s Instagram, below.

The foursome got together to celebrate Saget’s new Broadway show, Hand to God, which Culkin, Green and Grant attended earlier this week. The unlikely squad goofed around back stage and then headed on to Times Square where the selfie was taken.

“Fun times last night after show in the #TimesSquare with friends@ClareGrant, Macaulay Culkin, and the master of the selfie, my pal @SethGreen,” Saget wrote on the pic.

E! News has identified a common link that may have led to the trio striking up a friendship. Both Saget and Culkin have lent their voices to animated TV show Robot Chicken which Green co-created.
