Finally, something to smile about during jury duty!

Seventeen members of a Queens grand jury — plus one court officer — yesterday learned that their shared $2 Powerball ticket, bought with other tickets on Wednesday, hit for a nifty $10,000 payout.

“Sometimes it pays to do jury duty,” quipped Queens DA Richard Brown.

The jurors, whose identities are secret, beamed as they entered the Kew Gardens courthouse though sources said they were irked about missing the $587 million jackpot by just one number.

Still, each winner’s share is $555. And they got an extra bonus — being released from jury service.
