If they ever have a contest to find the world's best son, we've got a clear frontrunner.

This man paid off his mother's mortgage as a way of thanking her for all she's done for him.

The kind son posted a video of him getting the check ready to YouTube and then handing it to his mom, who was unbelievably touched by the gesture.

In the video, the man discusses how he may not be the world's best son, but his mother is always forgiving.

Making it even more awesome is the fact it was the man's birthday. He said, "I want to celebrate my life, by celebrating the woman who gave me life."

Now the man has a real dilemma: trying to top this gift come Mother's Day.
