Looks like you screwed with the wrong old man today, punk. I may look grey and infirm, but I'm packing a million volts of incapacitating, jaw-clenching self-defense. Or offense! This grandpa's crazy! The Zap Cane also has a flashlight. Beware!

In case you're actually in need of a cane for non-shock attack reasons, the Zap Cane is adjustable from 32 to 36 inches, and can support up to 250 pounds. The thought of a 250 pound person waving around a million volt stun gun is terrifying and incredible. Especially if the built-in LED flashlight is also turned on. [BUDK via Gadget Lab]
