All screwed up

I took my bike out of the car yesterday and noticed the seat post was 2cm low. I guess the crunch I heard was my big butt pushing the seat post down. This morning I was getting the bike ready for a short ride. I found out that I was missing 1 of 4 screws for the seat post. One of the other screws was loose and about to fall out. Maybe I am just all screwed up.
