While referring to [spoiler]Michael's "death"[/spoiler]in today's Ep #928, Julia opines that:
"Classically, it's almost classic, actually."
Yes, of course it was, Julia.
That line is definitely up there with Barnabas' line from Ep #386 when referring to accusations that Vicki is a witch:
"I am defending the right of this girl to be judged innocent until she is proved innocent."
They're not bloopers, per se, because the lines still make sense within their scenes - but it's pretty safe to say that the tounge-tied delivery was probably not exactly what was written in the scripts.
Anyone else care to share some of their favorites?
