Getting Stuck

I've been here before. Why have I never noticed this? 

I had to go for blood work today. On the wall of the lab, directly across from the seat where they prod you until they can find a vein with any life in it - and then jab you with a needle (hopefully only once), hangs this sign. 

You mean to tell me that there are people out there that actually want to pick out the needles that they, for some reason, think is the best one to be jammed into their arm? Are they arguing about this with the lab technicians? 

Not only that, but apparently there must be so many of these people, that the lab had to go out and get a special sign made up. 

Whenever I have to go to lab, I spend the entire time trying to not look at the needle. Now, I can't stop thinking about it.
