U is for unicycle. When I was a child I went through a period of time where I wanted one of these in the WORST way. I begged for it. My mother was usually a pushover when it came to begging... within reason. She never gave in to this request though. Maybe it was because we were already on a first name basis with the nurses and staff at the local ER. One more visit and I'm sure we would have been invited to their company picnic. There isn't an extremity on my body that hasn't been stitched up at least twice. I guess she just wasn't into finding out how they would treat a cracked skull. Thank God my kids never asked me for something like this.
