Mysterioii:
If you had a little more time to prepare I'd suggest an arduino plus a "wave shield" from adafruit. You'd have to do some coding... the wave shield plays audio clips off an SD card and you could hook up buttons to selectively trigger whatever audio clip you wanted. You'd have to add a small speaker and a battery.
Would take a bit of DIY and a little time to pull it together, but definitely doable.
ChadTower:
Hold on. How would you set up the individual switch lines? I have been poking around an idea similar to that for a different purpose.
Mysterioii:
Pretty easily really. The arduino has several GPIO pins.... you'd just need to define some as inputs then wire some pushbuttons to them.... your wire runs could be pretty long and it wouldn't hurt anything, if you wanted to put the pushbuttons on his belt or something. I would just put a pulldown resistor to ground on each input pin to keep them from floating, then connect one side of each momentary pushbutton to +5v and the other to an input.
Because of the pulldown resistors to ground you'll get a nice clean ground on each input when you don't press a button (otherwise they'd float and you might get some false positives). Then your code just needs to loop forever and constantly check the inputs. If you see a high, tell the wave shield to play the appropriate sound, then start checking for high inputs again.
ChadTower:
That could work. Thanks, man. That's pretty much at the edge of my current skills with this stuff.

Oh man I wish I had the time to do this.
