From head to toe, Keenan Watkins is the very definition of a "tough customer."

He's 6'2", with a huge fiery beard, tattoos and a shirt that says "Punisher" on the name tag. So when he visited a Goodwill last week carrying a baby doll in his arms, he raised a lot of eyebrows.

The store's greeter Sadie Collins asked for the story behind his unusual shopping buddy, and when he told her she just had to share it online.

His touching story was shared on the Love What Matters Facebook page, and after reading it people are calling Watkins "father of the year."

It turns out this tough guy is the father of 2 young kids, his 9-year-old son Ash and his 10-year-old daughter Aayla. While Watkins was making dinner last week, Aayla asked him to carry her baby doll, named Davey, around with him for a whole day.

Not realizing how embarrassing it would look to carry the doll around, Watkins agreed. That's when his daughter doubled down, telling him that Davey would need some new clothes and socks too.

"I should probably mention that at some point during dinner," said Watkins, "she had interjected the fact that Davey will need to be strapped in, everywhere we go. Because, you know... safety."

After Collins shared her photo of Watkins and Davey at the store, it went viral online and Watkins shared more photos of their day together.

"I'm just a Daddy that wants his kids to truly understand that I love them," he wrote in his post.

"I want them to be happy, and would gladly take on a potentially embarrassing situation, in order to keep my promise to them. Father of the year? Hardly. Father? You bet."

Despite how humble he is, people can't get enough of these silly photos of Davey and Watkins spending time together.

They really made a day of it, visiting the Goodwill and Walmart. Davey even got a sticker from the cashier, and a big container of cheese balls to pig out on.

After Watkins explained Davey to the people he ran into, everyone seemed to think it was a great idea. Except one little girl.

"She just [couldn't] wrap her mind around why this big dummy has a perfectly good doll that she could be playing with!" he said.

One thing is clear: Ash and Aayla are lucky to have a dad as sweet as Watkins!
