Well, not much. Considering one person is fictional meth kingpin and one person is one of the most known people in the (real) world.
But, according to TIME Magazine, both are pretty darn influential.
Pope Francis was named TIME's Person of the Year, after his papacy began in March of this year. A very worth candidate, and a whole heck of a lot more worthy than Miley Freaking Cyrus.
Walter White was named the year's most influential fictional character by TIME, and give how obsessed I've been with Breaking Bad, that's warranted too.
I just find it funny that can be mentioned in the same breath. But in all seriousness, looking back on 2013, they're definitely two of the biggest names.
And that is what you get when you google "walter white pope"
I love you internet.
