I never really noticed this, but, In later years, J.J.'s catchphrase was changed from "Dy-no-mite" to "You know, what can I say?"

Dynomite was no longer said once J.J stopped wearing the blue Hat

I guess I never noticed lol

In the later episdoes J.J. would answer the telephone by saying "chello". I think after "dy-no'mite", that was supposed to be the next catch phrase, but it never took off.
