Why does Tallahassee say that there are "six" people left in the world in Zombieland when there are only five?

In the scene where Tallahassee goes crazy about Bill Murray he says "There are six people left in the world, and one of them is Bill ****ing Murray!" This seriously messes with my head cause there are only five in the movie...who is this mystery sixth character? haha lemme know what you think :bWhy does Tallahassee say that there are "six" people left in the world in Zombieland when there are only five?
Tallahasse has actually no idea of knowing how many people there are left in the world that are not affected.

saying "There are six people left in the world, and one of them is Bill ****ing Murray" was prob just a figure of speech
Well there's a lot of buzz over that quote.... the speculation is who is the 6th one he is referring to?!

1. First of all, it might be a revealing mistake.

2. it might Bill Murray's makeup artist who taught him to do the zombie makeup.

3.may be Cynthia Knickerbocker, the nun who earned Zombie Kill of the Week about halfway through the movie.

4. the 6th one might be his enthusiastic reference to the zombies, infectious

5.May be he is hoping there is at least one person alive out there apart from the five of them.



PS: 6. Whatever who cares.........Why does Tallahassee say that there are "six" people left in the world in Zombieland when there are only five?
He probably did it on purpose just to eff with you! Tallahassee seems like the sort of guy who would do that. Funny guy to watch on film, but I bet I'd hate hanging out with him in person.
he WAS hit in the head with a golf ball... I think it was a subtle joke.
Yeah, I noticed that too. I don't know.
