All the more reason to request your wedding band to be like so. For me the strangest opening device would be when I was working on some chain maille and a friend brought me a beer, just rip the cap right off with the pliers I already had in my hand. Strangest drinking vessel? Recently would be my bottling bucket to not waste, on a longer time frame would be when Boston Pizza had their "Fishbowl Fridays" promotions.
