Multiple Sclerosis

"Born a mutant
Now we're talking! You can't lose your incredible abilities, your powers are powerful but quirky and unpredictable"

I love that, of course the mutation is benign and gives you powers, rather then say, cancer.

Multiple Sclerosis, now that's a badass power! Not just one, but MULTIPLE!!

I don't know if it's the obviousness of the joke or the truthfulness of the joke that makes it hilarious. That is just hilarious.
