Yes.  Extension, and polymorphism, just mean "type."  Weird is a type of 
Weird, so it fulfills the bound that the type of T must be a type of 
Weird (extends Weird).

Well, you didn't do anything with the type parameter T, so not a lot is 
happening.  Try to find some existing classes that use type parameters, 
like the Collections classes, and ask that question for them.
