WATCH: Sister Covers Little Brother in Peanut Butter

Kids are often the world's leading producer of messes. They are also a leading producer of adorable moments, and viral videos.

Further evidence of this idea appeared online earlier this week, as a 3-year-old girl was caught on camera covering her 18-month-old brother in peanut butter.

The video shows the siblings sitting in the center of the kitchen table.

The brother, Ethan, is covered in peanut butter. The sister, Emily, is caught red handed, with her hands and arms covered in peanut butter.

A nearly empty jar of peanut butter can be seen sitting on the table next to them.

Both seem a little concerned once an incredibly forgiving mother enters the room.

Check out the adorable moment below.
