Gratitude and good manners don't come naturally to everyone, so one father decided to see if his toddler required some teaching where those attributes are concerned.

To find out, dad Jeff Simmons wrapped up a less-than-exciting birthday gift for his little boy.

"It's an avocado!" Simmons' son exclaimed with a smile. "Thanks!"

That sweet moment said it all. Consider that test passed.

Simmons isn't the first father to come up with that sort of challenge for his children. Back in 2011, Tim Cocker presented his son and daughter with an onion and a banana as early Christmas presents.

Just watch the clip to see another big win for Team Kid.
