A friend back in Knoxville used to love to relate the tale of the time his car's transmission went out. As he was trudging along the road, he was given a ride by an obviously well-to-do older woman in a nice car.
They're driving into town and she asks him what happened to his car, and he explains that the transmission probably needs replacing. "Oh," she exclaims, "Ah'll just bet that'll cost like a wahpenzion!"
Caught off guard, he replies "Wow, I never would have taken you for a Trekkie! That's neat!"
"A Trekkie. A fan of Star Trek."
"Ah'm sure Ah don't know what you mean."
...because, of course, where his geek-like-me ears had heard "cost like a warp engine", she had used the old colloquialism "cost like a war pension."
