Is this innocent looking Cubs fan actually a vampire?

During the Cubs-Cardinals game Thursday, one [hungry?] Cubs fan took a chomp out of the woman sitting next to him, presumably his girlfriend/wife/sister, we hope.

This can only mean one of three things:

1. The cost of ballpark hot dogs is too high.

2. This Cubs fan is a vampire.

3. The cost of ballpark hot dogs is too high and this Cubs fan is a vampire.

In any case, it's probably safer just to watch the game from your couch from now on.

(Thanks to It's Always Sunny in Detroit for bringing this to our attention.)
