"Why are there so many Ostriches?": Originally said by Don Knotts on Family Guy, the term is used as an exclamation for not understanding stupid people. An Ostrich, for all intents and purposes, is not only a bird, but a person with no common or street sense, who will then lash out negatively towards a person who DOES have these qualities in thinking that they are smarter than them. (It is more fun and effective to say this phrase as similarly to Don Knotts as possible)

Upon seeing a person who doesn't know what music is, you then shake your head and proclaim, "Why are there so many Ostriches?"
