Marketing for cities

An acquaintance suggests the slogan:

You'd be bonkers to not stop off in Honkers

to encourage more people to have a night in Hong Kong on the way to Australia/London/wherever.  Obviously, this is good because it rhymes, and it suggests mental health issues - the two cornerstones of a successful advertising program.  Can we generalise this?
Depression: You'll be incredibly sad if you don't visit Baghdad
Tendency to domestic violence: You won't want to thump her, if you go to Kuala Lumpur
Poor self image: No self-worth? Not if you've been to Perth!
Anomie: If there's nothing about which you give a shit, don't bother coming to Split
Onanism: Visit Ulan Bator unless you're an obsessive masturbator

Any suggestions sincerely welcomed.  Apologies in advance for mispronouncing any of your cities for the sake of a cheap joke.
