The professor says that his goal is to be "accessible" with students. Ain't that the truth!

Daniel Krebs, from the University of Louisville, was photographed playing games in the hallway outside his classroom with one of his student's children during an exam.

Monica Willard, a junior ROTC student, has two children: 4-year-old Marcus and 5-year-old Mikayla. Her babysitter canceled last minute, and she says there are no military bases by U of L and the daycare centers aren't open at a time that works for her.

The class didn't even know that the kids were there, until Marcus banged on the door. Dr. Krebs said, "Don't worry. Go take your test. I've got them."

"A person like Monica, she's a non-commissioned officer going to school, she's a mom of two kids. I mean that's the kind of thing that's really impressive," Krebs told ABC News. "Me handling her kids for 40, 45 minutes, that's not impressive."

Monica asked one of her friends, Victoria Henry, to snap a picture (since the kids had her phone, of course). The photo has gone viral.

"A lot of professors just aren't as caring as Dr. Krebs is," Henry said. "Since military history is such a small class at U of L, he really got to know us on a personal level so we built that relationship with him outside of class."
