Foo Fighters

Glad you think so :) I think they're actually Russian

There's more than one Fighter, so wouldn't it be "Who are the FOO"? LOL

You would be correct but explaining grammar to an alien that believes mustard can be enjoyed as a beverage isn't exactly on my list of strong points XD

Okay.....valid point! Especially since I've been marathon-watching X-Files episodes on Netflix!

Isn't it a reference to aliens?
