"You are probably more likely to see bedbugs in crowded low income residences for the same reasons you might find them at an exclusive Manhattan hotel."
There you go, infestations know no bounds and being small and in hiding the critters are awfully hard to spot unless you know just where to look for them so are easily transported. The "plague" started ages ago and when it became epic the song was written. You don't think that "uptown" refers to Harlem now do you? I have serious doubts the Stones shacked anywhere but in a five star hotel when they played New York.

Don't you know the crime rate is going up, up, up, up, up
To live in this town you must be tough, tough, tough, tough, tough!
You got rats on the West Side
Bed bugs uptown
What a mess this town's in tatters I've been shattered
My brain's been battered, splattered all over Manhattan.

What bugs me (pun intentional) is the state recently issued a notice regarding the wing of a local hospital run by a major hospital "chain" where group therapy sessions are held. According to the state it's infested up the wazoo yet outpatients are still meeting there and bringing critters home with them infesting their places of residence. Now there's a twist, even if they get rid of them in the home they'll keep coming back as long as they continue to attend until and unless the facility is completely rid of them. I feel the building should be vacated and fumigated but the facility continues in operation, oh well.

Oh and BTW, Ozzies may be tough but do you really like being bitten by disease carrying miniature vampires? Yeah mate, they consider you lunch!
