"In WWE(1)I noticed a larger than usual group of offhand lines (ethel
.../wait in car.../cool-you know what I'm talking about). Was this
scripted? Or was someone just ad libbing?"

There's almost NO ad-libbing allowed on the show. You can't change a word
unless someone comes to my office and approves it, and it can't change the
meaning. (I.e., the actor is having a hard time saying "shibboleth" or
something.) Everything said in this show is scripted, offhand comments
included.
