A brief moment of cane-fighting: after using the cane at middle distance (kick, maybe punch range), we decided to see if it could be useful at trapping/grappling range. After a number of attempts ending badly (from my perspective; uke was happy), I took the crook in my hand from underneath, inserted the tip of the crook behind uke's collarbone, and pulled down as though I were trying to get a semi to honk at me. Uke turned white, collapsed, and refused to play anymore.
Soon I'll have a chance to see what airline security thinks of the cane. I plan on playing Tiny Tim. Sans ukulele.
