Actual things Im guilty of, I broke a rule or two as a youth.
Visit the stereo section, set the alarm function for 5 mins on every one you can, crank the volume and walk away quickly.
Run up n down the grocery isle with pilfered razor blades from hardware slicing open packages.
Find the 6volt lantern batteries; pull off the plastic covers on the springs.
Turn battery upside down and stick behind some plates on a metal shelf.
[non flammable stuff, starting fires isn't cool]
