Don't freak out if your evil twin wreaks havoc on your life.

Getting mad never solved anyone's problems, except for the Hulk.
But remember that it also created new problems for him as well.

Sure, it solved the issue of bullets hurting him, but what about the trouble of how many pairs of pants he had to buy? Or steal, probably.

Of course, if he didn't turn into the Hulk and got shot with bullets, he would probably bleed all over his pants and need new ones anyway.
(Along with the rest of a suit to be buried in.)

So, to sum up:
Don't freak out, unless you're the Hulk.
Then it might be okay, but still likely a mixed bag.
(Maybe try to solve your problems with science first. Be smart.)
