Every Young Israel has a Yek. It's a fact. The person doesn't even have to be an actual Yeckie to qualify. There is generally one main qualification:
On Friday afternoon, at 7:14, the Yek will run into the lobby shouting "ONE MINUTE TO MINCHA! LET'S GO! EVERYBODY INTO THE POOL!"
There are other things the Yek of the Young Israel will do, like when the guy who is davening Pesukei D'Zimra is going a little slow and will probably not make it in time for Z'man K'riyas Sh'ma, the Yek will go over to him and quietly (but with a lot of grandiose arm motions) implore him to go faster.
He will also generally be the one to first correct the Ba'al K'riyah when he makes a mistake. It's not that he wants the credit for it, he just doesn't want to wait any longer than absolutely necessary to get through leining.
A quick shout out to all the Yeks out there. This one's for you!
