Funny/awkward audio book goofs?

I was listening to the Heir to the Empire audiobook last night and reminded of/heard a couple of awkward things that just tickle me whenever I hear them. The first is the somber use of the Darth Vader funeral pyre music in the first chapter when Captain Pellaeon describes the many exemplary space Nazis who died when the Executor was destroyed. The other is when Marc Thompson refers to no "delta-five" instead of "delta-v" when Luke dead drops a torpedo to escape the tractor beam.

Anyhow, any other quaint little goofs in the audiobooks you enjoy?
