Embarrassed Himself In Front Of The Whole World
There are a significant number of people in the world who are woefully ignorant regarding the functioning of the food chain. However, very few people put such a high level of confidence in something as ridiculous as this. If people go to the supermarket to get their food, what is the point of growing crops?
A person who has an inflated opinion of their own intelligence is the only person who is capable of asking a question as stupid as this one. Nobody else in the world would ever be willing to put themselves forward in such an ignorant manner in front of everyone else in the world.
