Not so much that they bent the $hit out of them. They definitely yanked and cranked them. Guess that's what happens when Naval Aviators show what they can do with a jet!
I believe those were the F-16Ns, the highest performance F-16s of them all. They were grounded after 5 years, and completely retired after 7. AFAIK, the ex-Pakistani F-16A/Bs are still in use. Of course, they aren't flown like the Ns were.
