Regist-er-ation

A southern dialect for the common word, registration.

Regist-ER-ation

(police officer) I see that you were speeding sir, may I please have your license and registration?

(speeder) I certainly do have a license dear officer, but as you can clearly see it was so goddam hot outside, that my regist-ER-ation caught fire while resting in the dashboard.
