### Chalk One Up For The Grandparents!

An elderly man in Miami calls his son in New York and says, "I hate to ruin your day, but I have to tell you that your mother and I are divorcing.

Forty-five years of misery is enough."

"Pop, what are you talking about?" the son screams.

"We can't stand the sight of each other any longer," the old man says.

"We're sick of each other, and I'm sick of talking about this, so you call your sister in Chicago and tell her," and he hangs up.

Frantic, the son calls his sister, who explodes on the phone, "Like heck they're getting divorced," she shouts, "I'll take care of this."

She calls her father immediately and screams at the old man, "You are NOT getting divorced! Don't do a single thing until I get there. I'm calling my brother back, and we'll both be there tomorrow. Until then, don't do a thing, DO YOU HEAR ME?" and hangs up.

The old man hangs up his phone and turns to his wife. "Okay," he says, "They're coming for Passover and paying their own airfares."

### First EPA air pollution injunction

In 1971, in its first such action, the U.S. Environmental Protection Agency (EPA) shut down heavy industries in Birmingham, Alabama, when air pollution on this day was reaching dangerous levels. It was an emergency action under the Clean Air Act (1970). The EPA asked a Federal judge to issue a temporary restraining order. Among others, U.S. Steel had been belching too much smoke into an atmospheric inversion (stagnant air mass). Among idled workers, one said, “we're going to choke to death before we starve to death.” Six months before, the city had suffered a five-day crisis that spiked on 20 Apr 1971. At that time, while the state failed in enforcement, the EPA was not notified early enough to start emergency action. Days with high particulate counts in the air thereafter drew close EPA scrutiny.«
