If you see a menacing, Geraldo-looking guy pushing a stroller on the subway, CALL THE COPS IMMEDIATELY. IT IS NOT GERALDO. HE DOESN'T TAKE THE SUBWAY; HE HAS A BENTLEY AND A DRIVER.
On the other hand, if you see a shortish, kind of nebbishy guy in a suit on the subway, DON'T CALL THE COPS. It's probably our billionaire mayor Michael Bloomberg, who could buy Geraldo a thousand times over, but takes the train every day.
Even on days when terrorists are supposedly plotting to explode stroller bombs on them.
Also, if you're a swarthy-looking guy pushing a stroller on the subway, get a haircut or prepare to be searched, hippie.
