Less intelligent than an ape?

It's pretty obvious Goo has identity issues. We've
seen the Goober post and think of himself as a number
of "different" people, such as:

Jonathan Ball
Citizen
Benfez
Wilson Woods
Radical Moderate
Bingo
Edward
George
Bill
Fred
Mystery Poster
Merlin the dog
Bob the dog

As yet it seems most likely that Goo is posting as
the "Dutch" character as well. Goo refers to other
people using names with which they refer to him, 
strongly indicating confusion over his own identity 
and problems with making a distinction between 
himself and others. That's also indicated by Goo's 
strong tendency to tell other people what they think.
The Goober's lack of appreciation for his own
existence:

"coming into existence didn't make me better off than 
I was before." - Goo

is certainly further evidence that Goo has some
sort of identity problem. Since Goo believes animals
who don't understand reflected images must also 
have no sense of self:

"Dogs, cats, cattle, almost all animals "lower" than 
the great apes have no sense of self." - Goo

maybe we should consider that Goo with all of his
issues might not have any either...that Goo may 
be less intelligent than an ape...
