I swear to God this actually happened, well after me and my Dad finished watching T.V. our secruity alarm suddenly went off for no reason, my Dad shut it off but then 3 fire trucks showed up at our house! firemen actually came in to take a look at our house to see if anything was wrong, good thing there wasn't.  But still man, this sorta freaked me out, I mean wouldn't you be a little freaked out?
