Answer this to be called the smartest ... What has 4 lags in the morning, 2 in the afternoon, and 3 at night ... ?

A person

Step-by-step explanation:

I have heard this riddle multiple times, it is very well known and (in my opinion) very intriguing;

If we are considering the 4 legs in the morning, we can assume it to be a baby crawling on all 4's. 2 legs in the afternoon represents a more elderly person, a young child or adult on their 2 legs, and 3 in the night models an elderly person, using a walking stick as their " leg "

Answer; In other words, a person has 4 legs in the morning, 2 in the afternoon, and 3 at night
