If you have no further need for your basic, human dignity, get the latest humiliation device for iPad—in the form of USing Karaoke. It supports MIDI files, so you'll never run out of tunes to recreate that stuck-in-an-elevator-feeling.

For $2 you also get an accompanying file manager to load MIDI karaoke files into the app via Wi-Fi and Bluetooth, plus there's a BPM modification tool for speeding up the rhythms—for when everyone's self control is lying on the floor of the kitchen, soaking up all the spilled German lager.
