The 4 1/2 Day Workweek

At the last company I worked for, they had a nice system: about every two weeks they'd find some excuse for the company to pick up the bar tab after work. A big percentage of people would go, but you didn't have to. Some people would be there right at the start, others would show up later and you could leave whenever you wanted to.
Coffee areas with couches also payed big dividends -- again, the idea was that you'd yack with your coworkers, but only when it fit in with your work schedule.
But, I agree that a lot of corporate environments could not pull this off. There is a point in every companies life where the culture becomes too divided. Not everyone likes fantasy football, Mario Kart, Rock Band, Medieval themed restaurants, or volleyball, and any formal attempt to get everyone involved in any one of those things is destined to failure and poor morale.
A pretty large percentage of people, below a certain age, can agree on free beer, so the "picking up the tab" policy is a somewhat safer choice, but probably a less productive one. Do you really want people discussing business strategery after four or five cocktails over the sounds of the football game on one side and the jukebox kicking out Justin Timberlake on the other?
As far as "break time" goes, we really don't care exactly how or when you accomplish 4 days of work, but we do want 4 days of solid work to be accomplished. Some of us are night owl's and others rise at first light. Nobody's going to freak out at you unless you're really slacking.
If you want something which works as well in your business, don't just mindlessly clone this, or the 37signals 4-day week, or the first-stage startup 80-hour deathmarch, or any existing schedule -- work it out for your own environment.
Personally, I've been doing a lot of tweaking of my own schedule at work over the last year, and found that having at least one full day a week where work from home is a big booster to my productivity. It's an entire day where I can avoid random interruptions, and I never have that meeting in the middle of the morning that basically wastes the day through lunchtime.
Though the Wufoos are more fun than most people I've met, so they can probably make Fridays into a vacation without having to actually be free from work. I suspect not many employers have a comedy goldmine like Kevin, Ryan, and Chris around to tap into. (And, if they do, they probably think of them as a problem to be managed into submission rather than given a raise and put in charge of something.)
