Quick! When is President’s Day? What day will Labor Day fall on this year? If you celebrated MLK, Jr. Day this year by getting pissed off that the post office was closed on a Monday, you’ll want to bookmark this one: At PostOfficeOpen, a simple layout lets you know whether the U.S. Postal Service is open today, and whether it will be open tomorrow. Trust us, it’s a lot easier than trying to navigate federal websites. It’s hard to explain this website, and it’s even harder to explain why you’ve been watching it for ten minutes in a row. Procatinator is what happens when the Internet is distilled into its purest form — namely, animated cat gifs combined with short, obnoxious audio clips from hit songs of the past 30 years. Visit Procatinator and you’ll be treated to a repeating image of a cat made famous by the interwebz, paired with an appropriate (or not) song. A fat Persian eating a banana is given the track “Bananaphone;” a frantic cat chases a laser beam up a wall to the tune of Vitalic’s “You Prefer Cocaine.” “Walking on Sunshine” is the soundtrack for a tabby trotting along a treadmill. Click on “Show me another cat” to keep the performances coming, and please, if you’re at work, put some headphones in. And don’t do it on a day you really need to be productive. They don’t call it the Procatinator for nothing. Here’s a site about cooking with beer, except that it’s not run by a bunch of potbellied hipster guys screwing around with canned Milwaukee’s Best, a backyard hibachi and a whole chicken. Beer Cook is run by Lucy Saunders, the craft-brew expert and journalist who’s written five cookbooks on the subject. The site won a silver medal for Best Food Writing in 2002, and in addition to articles about topics like grilling with beer, weiss weddings and beer-and-cheese pairings, the recipe search engine is organized by ingredient, menu type, cooking time and more. Skip the PBR-and-PBJ ritual and try making spicy IPA beef jerky, beer doughnuts and cheesy Wisconsin gorgonzola ale sauce. Need five bucks? Please stop panhandling outside the bar; you’re making all the smokers nervous. Instead, head to Fiverr where you can put up something for sale for five dollars. (Legal, please — although if there’s anything illegal you’ve got that you’re willing to part with for a fiver, we’d like to see it.) Recordings of “Happy Birthday” sung in a sexy voice, cartoon portraits, dog-training advice, feng shui consultations, a song-and-dance done in a full-body cat costume — whatever it is, you can sell it here for $5. Got five bucks? Here’s the place to spend it, especially if you’re in the market for felt bunnies, customized LEGO people, banjo recordings or step-by-step bread-making video tutorials. This one’s a lot of fun — easy to spend five bucks, but easy to make it back, too. Photo by: justinwdavis
