AWESOMENESS !!
#4 (flood in the city) is my favorite, followed by apocalypse & stampede
find a pithy punchline for #4 and You'll rock to the frontpage!
something like 'to much water for my bubbles' or 'I didn't lock the bathroom' - whatever.
think about it - I'm sure You can improve my suggestions or show up with your own.
I won't do it for You nor capture it on my own - just leave it up to You :)
