You could say that the stainless steel Hulk Radiation Symbol Avengers Ring is quite RAD-ioactive, get it?  Get it?  Brandishing both the Hulk's radiation symbol on top and the Avengers symbol on the side, this is not the correct ring to wear to your Defenders meeting.  It's hard to keep things straight when you're on multiple super-teams, but this ring will help you do it.  Just make sure you take the ring off before you SMASH!
