How to get them: The W is distributing tickets (up to two per person) on a first-come, first-served basis through www.eventfarm.com/WDCThievery beginning at noon on Thursday. You have to be 21 to attend.

How to get them if that didn’t work: Oh, yes, there’s always a Plan B. We’re expecting these to go fast, so we’ll be giving away a pair Thursday at 1 p.m. during our Going Out Gurus chat. (To get them, we’ll probably make you write something to make us laugh, because that’s part of the fun.)

And beginning Friday, the W will give away a pair a day for 10 days on its Facebook page.

For those folks who’ve been to the Happenings bashes before (including the Pains of Being Pure at Heart afterparty this spring), there will be one major difference: The homegrown duo in Thievery Corporation will be spinning in the W’s Great Room ballroom.
