Three Pennsylvania men made a calendar for their mom as a Christmas gift by recreating old photos from their childhood.

Now two million people have seen "three grown men in a bathtub".

Their mother, who maintains very close relationships with her "boys" loved it. She laughed and laughed, and afterward came tears.

The photos were a big hit on Reddit.com where the older brother, Matt MacMillan, shared them. The men had plenty of pictures to choose from, and got their father to recreate a couple, too, like the heartwarming kiss below.
