LOL I'm with Lex on this one -- I don't usually don't charge, er change, my O rings on anything, unless I have to. Doing so has been known to make me up my nic level for a day or two. 
I do confess, the new silicone, glow in the dark and neon rings at HOH sure are enabling me to want to tackle the project. I even obtained a "dental pick" tool to assist in the task.
