FYI
 
A couple of... and a couple are also two different  parts of speech.  A 
couple of is a quantifier which is an adjective.   A couple is a noun. 
 
There are a couple of apples.  This is plural  because couple of modifies 
apples which is plural.
 
There is a couple.  As a noun, couple is singular  because it is a collective 
noun.

Knowledge is the seed that exists in all of us.
It is up to us  to cultivate that seed.
There is no such thing as a stupid seed.
Just as  there is no such thing as a stupid person.
