Telling vignette

The other day at work I noticed a co worker gazing upon my 2013 Porsche Cayman.  He approached me later on and said, "Wow, that car has some beautiful ashtrays." I thanked him for the compliment and walked away confused. 
At this point you may be questioning my co workers sanity, and rightfully so.  But fortunately, that conversation never happened and I don't drive a Porsche, I drive an 84 Toyota pickup.
So while that conversation never happened, one very much like it actually did.  A co worker approached me the other day and said, "Hey, I met your wife. Man, she is really pretty, I mean really pretty.  How did you manage to snag her?"  While I wholeheartedly agree with him, my wife is very beautiful, his saying so is comparable to the Porsche comment.  Why mention something as trite and shallow as external beauty when other things are so much more valuable?
Marrying a woman for her looks is comparable to buying a Porsche for its ashtrays.  While it very well could be that a Porsche does have nice ashtrays, who cares?
To find a godly wife is more valuable than gold.  To find a vain wife is a grief that will last a lifetime and worsen as time goes on.
The vanity of the world and the love for things temporal will not satisfy or lead to joy.  Why build up what so quickly disappears?  Why spend so much time and energy on something so short term when the state of our eternal souls needs so much work?  Why polish the ashtrays when the engine won't even turn over?
