I have a collection of my son's plectra found in various places around the house, so for his Christmas present I gave him a South Park "Son of a bitch" plectrum. (OK I said it!)

Oh and don't put your plectrum in supermarket trolleys in Makro, as they transfer all your purchased goods into another trolley as you go through checkout, so you end up with the trolley with no plectrum in it!
