Guy 1: “hey what’s the opposite of a waterfall?”
Guy 2: “what? why do you need to know?”
Guy 1: *sweating intensely* “it’s really important just give me the answer”
Guy 2: “um I guess it would be called a firefly”
Guy 1: “thanks” *proceeds to run away into the darkness*

Firefly

A Great Song by "Breaking Benjamin"

Firefly Could you shine your light
Now I know your ways
'cause they're just like mine
Now I'm justified
As I fall in line
And it's hard to try
When you're open wide
