Vortex of Evil

This morning, whilst I peacefully drank from a bottle of water, a strange thing occurred. I was trying to replace the cap to said water bottle with one hand, and it slipped, falling to the ground. I have no idea what happened to it. It fell straight down, made a sound like it landed flat somewhere, and now I can't find it. It has been driving me insane for the past hour and some odd minutes. I can't hardly think straight. My office is not that big, and there is not much stuff in it. I have crawled around on the (disgusting, bug-infested) floor of my office looking for it. I can't do anything for more than a few minutes at a time without looking down at the floor for it. Has anything like this ever happened to anyone else? I cannot see any conceivable way that this is possible. It is a mystery. Mabye it was swallowed by a vortex of evil.
