When apps first became all the rage, we all rolled our eyes at the plethora of fart apps. And there are still plenty of those to go around. But developers have developed their sense of humor since 2008 to encompass a much wider variety array of silly apps. We've dug up the 10 best of those time-wasting, weird and downright bizarre apps to come out on Android or iOS devices.

The Hodor Keyboard ( Android) ($0.99)



Now, you too can match the eloquence of Hodor, the gentle giant of the Game of Thrones series, with the Hodor Keyboard, a one-button Android keyboard app that lets you go "Hodor" (or "hodor", or "HODOR" to your heart's content. From the description: "Extra bonus: If your passwords are Hodor, this is by far the fastest way to log in."

The Most Useless App Ever ( Android) (Free)



This app is exactly what it says on the tin: The most useless app ever. Unless you like pressing buttons that do nothing. In which case, this app is perfect for you. At least, unlike the infamous "I Am Rich" app, this one has the decency not to rip you off a few hundred dollars.

iFrenchKiss ( iOS) (Free)



Do you require quantitative, scientific analysis of your kissing technique? Well, there's an app for that. iFrenchKiss claims to use a proprietary "kissing analysis engine" to rate your skills with the French kiss and the classic smooch. All you have to do is make out with your iPhone screen. To quote the app description: "Use common sense and do not slobber all over the device."

MyRazor Lite ( iOS) (Free)



You can now pretend that your iPhone is an electric razor with MyRazor Lite. We despair for the human race when we realize that at least some reviews for this app are complaining about how this doesn't actually shave your hair with the iPhone. Then again, that could be the next killer iPhone feature. Who knows?

iBeer ( Android, iOS) (Free)



Being the designated driver sucks when everyone else is having a drink or two and having a great time. Enter iBeer, the app that lets you pretend to knock back a cold one with your smartphone's touch screen completing the illusion. Using your phone's sensors and some visual trickery, the app realistically mimics a glass of beer. Tilt to drink! It even comes with a realistic burping noise to complete the illusion.

Yo ( Android, iOS) (Free)



We can't quite tell whether Yo is the stupidest or most brilliant thing ever. It's a super-simple messaging app that really only does one thing: just select a contact and the app sends a simple "Yo". Mind-blowing. So mind-blowing that it's actually managed to secure $1 million in seed funding.Brilliant? Stupid? Addictive? We'll let you make the call on this one.

Cooling Fan ( iOS) (Free)



The Cooling Fan app is the perfect companion on a hot summer day...or not. Probably not. Still, it is cute, with multiple backgrounds, multiple fan wing designs, speed levels, and sound effects.

Zips Lite ( iOS) (Free)



Zipper fans can now zip a pair of jeans up and down ad nauseum with the Zips Lite app, which displays a virtual zipper on screen. Slide it up and down to zip or unzip. Users can choose from a selection of men's or women's undergarments that can be displayed as the zipper slides up and down, and users who splurge a dollar on the premium version can select custom images from their camera roll. And yes, of course, people have used this for dick pics.

The Ministry of Silly Walks ( Android, iOS) ($0.99)



And now, for something completely different. Well, okay, not really, this one's just as silly as the rest, we just wanted the excuse to use a classic Monty Python catchphrase. Inspired by the classic Python skit of the same name, The Ministry of Silly Walks is a spin on the infinite runner where players take a jaunty stroll around town showing of their silly walks while dodging pigeons and obstacles and collecting coins which can be spent on silly suits and power ups.
