Now, I know the title seems strange, but let me explain...
The zombie part comes from the fact that Aaron recently has been obsessed with an iPod touch app called Plants VS Zombies, where zombies are attacking your house and trying to eat your brain, and you have to defend it by planting zombie-attacking plants.
The capture the flag part comes from the fact that we signed Aaron up for flag footbll and he confused it with capture the flag.
The following conversation was like this:
Me: So in capture the flag, there's two teams, and they each have flags. They hide the flags, and then the other team tries to find it without getting tagged, because if you get tagged you have to go the their jail. If you get their flag then get onto your side, you win.
Aaron, confused then understanding: Oh! So it's like if a zombie breaks into your house, steals your brain, takes it to the other side of the road then eats your brain.
Well, I guess that's one way of putting it...
