What do you call a group of ethnically diverse disabled people?
Seasoned vegetables.
Listen up, chucklehead. This joke is saying that a group of "ethnically diverse disabled people" are called "seasoned vegetables." Get it? Because "seasoned" means both experienced and spiced, and vegetables... well, you probably think vegetables are people too, don't you? Look at you, still laughing... I bet you wear a helmet when you eat soup, don't you?
