Background about the song: One day, I was getting so sick and tired of seeing the small flies, or gnats as they're really called, that I decided to get some water spray and spray their wings until they're heavy enough for them to fall to the ground, where I can just step on them. I sprayed one of them so hard that the gnat stuck to the wall, and I smashed it. Well, after I smashed it, it looked funny the way it was smashed. That's how I decided to do a song about something stupid like that.
Where the humor in the recording comes from: The person rapping the tune makes fun of the whole thing by making weird suggestions such as cutting up a piece of the wall where the smashed bug lies and selling it on ebay.
