What's in a Name

at first, he was called simply Bruce
for reasons that are quite obtuse
they changed his first name
to David, when tame
and Bruce fell into full disuse

At least so it was on TV
But Norton, and Ruffalo’s spree
Restored the old name
Our Hulk, still the same
When angry, he’s something to see
