This awful figurine from the SAW movies is actually a pretty cool 30 second sample/playback module that's easy to hack. You can buy them <a href="http://www.allelectronics.com/make-a-store/item/SAW-3/SAW-3-DIGITAL-VOICE-RECORDER/1.html">here</a> for $2 a pop from allelectronics.com. It's almost worth the $2 just for the AAA batteries that come with it. 

Add audio IN and OUT jacks, a pitch control and a loop switch using the schematic shown below.
