A friend of mine had that conversation with his young son this week. Though in their exchange, I believe the term of the moment was "ding-dong."
I'm not sure what they finally decided. But the question raises additional issues.
Is the Hulk's junk green?
Does everything, uh, change when the Hulk becomes the Hulk?
If the answer to the question in the headline is "No," does that partly explain why the Hulk often seems so angry?
Is the Hulk's whole deal simply a matter of compensating?
