It was a TV series I watched when I was very young. It featured three very cute and adorable triplet little boys.
It seems that their parents, who are actors, couldn't take care of them for a while, and then handed over the task to a friend - a super funny grown man.
So many little stories happened between these three children and this grown man.
One of the scenes that had the most profound impact was when these three little boys refused to eat, but they very cleverly said that they had eaten.
So the helpless uncle used the most primitive method to detect whether they had eaten - weighing everyone before eating and again after eating.
It's a steel scale used to sell things.
