I like to backup my wallet.dat to multiple usb sticks and put them in seperate jam jars. I then get my face painted as a puppy and stick on some impressive looking whiskers. The fun part is digging new holes in my garden to put them in. I also occasionally indulge in digging up old ones to verify them. I do a lot of growling and sniffing during these rituals, but I think it's more my tourette's than anything. TBH the verification digging up bit is pretty much all OCD.
