mrsmac no they most certainly are not
Rocky Mountain Oysters are Bulls Testicles. I have never tried them myself and probably never will, but the people I know who eat them absolutely love them.
rawcalls hang in there. I know we have members who do eat them and will be able to give you an idea how many people 10lbs will feed.
OK here is a little joke on topic.
A tourist was in a restaurant in Spain. He sees the waiter bring out a plate with two large orbs on a plate. It looks very tasty so he asks the waiter what it is. He is told they are Rocky Mountain Oysters. The next day the tourist goes back to the restaurant and decided to order the RMO dish. When the waiter brings out his plate there are two very small orbs. He is very confused and asks the waiter what gives. Yesterday when I was here they were huge. The waiter responds "Senor, sometimes the bull wins".
(OK I am horrible at telling jokes so I hope I didn't butcher that one too much)
