Are you familiar with "hard lemonade"??

If not, your children can be taken from you...

If you watch much television, you've probably heard of a product called Mike's Hard Lemonade.

And if you ask Christopher Ratte and his wife how they lost custody of their 7-year-old son, the short version is that nobody in the Ratte family watches much television.

The way police and child protection workers figure it, Ratte should have known that what a Comerica Park vendor handed over when Ratte ordered a lemonade for his boy three Saturdays ago contained alcohol, and Ratte's ignorance justified placing young Leo in foster care until his dad got up to speed on the commercial beverage industry...

Ratte is a tenured professor of classical archaeology at the University of Michigan, which means that, on a given day, he's more likely to be excavating ancient burial sites in Turkey than watching "Dancing with the Stars" -- or even the History Channel, for that matter.

The 47-year-old academic says he wasn't even aware alcoholic lemonade existed when he and Leo stopped at a concession stand...

"I'd never drunk it, never purchased it, never heard of it... And it's certainly not what I expected when I ordered a lemonade for my 7-year-old."

But it wasn't until the top of the ninth inning that a Comerica Park security guard noticed the bottle in young Leo's hand.

"You know this is an alcoholic beverage?" the guard asked the professor.

"You've got to be kidding," Ratte replied. He asked for the bottle, but the security guard snatched it before Ratte could examine the label...

An hour later, Ratte was being interviewed by a Detroit police officer at Children's Hospital, where a physician at the Comerica Park clinic had dispatched Leo -- by ambulance! -- after a cursory exam.

Leo betrayed no symptoms of inebriation. But the physician and a police officer from the Comerica substation suggested the ER visit after the boy admitted he was feeling a little nauseated.

The Comerica cop estimated that Leo had drunk about 12 ounces of the hard lemonade, which is 5% alcohol. But an ER resident who drew Leo's blood less than 90 minutes after he and his father were escorted from their seats detected no trace of alcohol.

"Completely normal appearing," the resident wrote in his report, "... he is cleared to go home."

But it would be two days before the state of Michigan allowed Ratte's wife, U-M architecture professor Claire Zimmerman, to take their son home, and nearly a week before Ratte was permitted to move back into his own house.
