Some boys in Harlem got a special lesson that made this Father's Day one to remember.  NY1's Cheryl Wills filed this story.

We can't show their faces on the air, but the fingers of a group of Harlem boys really do tell the story.

Workers with the city Administration for Children's Services are teaching them a different kind of lesson.

It's a special workshop on the ins and outs of tying a tie and a bow tie.

One teen is preparing for his prom – but he's going to take the easy way out.

"I got a clip on bow tie," he says to laughter.

This was first for these curious boys, most of them from broken homes.  And it was a "show and tell" for a group of ACS officials, who said they were delighted to teach some of the city's most vulnerable children the tricks of the perfect knot.

"Anything that I would like for my own son, we would like to provide it or service the community with these benefits," said ACS Deputy Director Ducoste Lamothe.

The event was the first of its kind at the ACS field office in Harlem, and as a special treat just for Father's Day, every child got to take home a tie.

"Everyone loves their father or significant male person in their life, so it's important that we recognize their involvement in our lives," said ACS Supervisor Lydia Hyatt.

The young men admit that they will need more than one lesson to get it just right.  But getting a helping hand from these strong seasoned hands was an awesome way to celebrate fatherhood.
