Actor Steve Guttenberg, who you might remember as Mahoney from the Police Academy movies and the gay one from “Three Men and a Baby,” enjoyed an afternoon constitutional through the park sans pants while training for the New York City Marathon last month. It’s the very realization of everything that my grandma feared about the Big City — pantless Jews with blurry genitals accosting innocent passersby in the park. But the way Grandma always told it, there should have been a gang of thugs with a taste for white women wielding shanks and a couple of post-op transsexuals fornicating on a park bench. The City That Never Sleeps is also The City That Never Wears Pants, she always said! That’s why we decided in the end to have Grandma put down.
