I'm not usually a fan of "novelty" apps, but this one caught my eye and I think it's pretty amusing. Now Serving is a deli-counter style counter for your BlackBerry. If you're having a bad day at work or being bothered by family and friends, this app is a great way to say "Hey! Take a number!". Now Serving is as simple as it gets - just click the Add button or press any key and the counter goes up by one. Leave your device in the charging pod, start up the app and have your very own counter with no effort. Granted it's still more of a novelty than anything else, but it could be good for some laughs. Now Serving sells for $0.99 in the CrackBerry App Store. Roll of numbered tickets not included ;-)
