Holiday party time, that is, when businesses throw their annual bashes. Sometimes they are strictly employee events - rewarding everyone for their hard work by taking up some of their leisure time during an especially busy time of year. Sometimes they are also intended to impress the customers and potential customers.
That's fairly common in the ad world. And of course when you're an agency, you need to demonstrate your communications and savvy and coolness with a great invitation and hot party.
Of course, you might decide to be edgy. That can result in stuff like this video from TBWA\Chiat\Day NY (what is with those stupid backslashes in their name?). I've linked to a description of it, not the actual video, because you might not want to watch it, given the prominence of projectile vomiting as a theme.
Does this make anybody want to spend money with these folks? Or even stop by for a cocktail?
Maybe I've just become an old man at last. I look at their name, and think something sarcastic about how if you have to use weird punctuation to be distinctive you're probably running on E in the creative department already... and then I watched the video and thought, "I wouldn't want to be stuck in an elevator with these folks."
Maybe I'm just missing the joke here.
