Non-damaging, but severely annoying things you can do after you free your bike w/the aforementioned hacksaw:
Vaseline the handlebars
Buy a cheap length of chain and padlock and attach it to their bike. Whether or not you attach their bike to something with it is up to you...
Re-adjust their low limit screw so that they can't use their granny gears
Adjust the saddle height/tilt/fore/aft
Un-center their handlebars

...you get the idea. Be creative
hehehe you guys are awesome! The newspaper idea too...
