Yes, I've been informed it's something like that, but I did not see that either.
To me the joke poses still another problem for understanding.
If one should ask me " What is the difference between 'a great tuna salad sandwich' and 'great sex', I would say: " None ".
I see no difference between 'great ' and 'great ', but that's a personal point of vieuw. I'm as bad at understanding jokes as I'm at mathematics, (most of the time)
