What is the motto of the 'Mentally Challenged Vegetarian Club'? You are what you eat!
Wow, it's offensive to suggest someone with mental challenges is a vegetable. What does it have to do with being vegetarian?
The motto of Mentally Challenged Vegetarian Club is "You are what you eat". That's the joke. It means if you are a moron, you are probably vegetarian too.
Mental illness have different kind of severities. Some of them can live a full life and others cannot.
Everyone knows that. That why it's a joke. Besides, vegetarianism only works on crazy people.
You shouldn't call someone mentally ill in any way, whether it's based on intelligence or sanity, just because of their diet. Vegetables are healthy and vegetarians can get all the nutrients they need to live a healthy life. People with mental illnesses can also think and act, so calling them vegetables is offensive and short-sighted.
