An "Old English Accent"

In this article about people auditioning for the Sarasota Medieval Fair, we're told of one of the castmates:

"I'm going to do everything correctly with your daughter, at least twice," he declared in a broken, old English accent.

Uh, I'm guessing they just mean "fake English accent" -- what would be an "old English" accent? And how could that accent be "broken?"

There's a photo gallery of the auditions here, and if you want to see a REAL Old English accent, there's one below.
