The wife and I were trying to have children. She finally talked me into having a male fertility test. So I went to the clinic and told the nurse what I was there for. She handed me a little paper cup, no magazine or anything, mind you, and pointed me towards the bathroom. I went in and did what I had to do. I confess I stayed in there a few extra minutes so she wouldn't think I was a rabbit. Then I came out and handed her the cup
She looked in it and said ' Um, we only wanted a urine specimen ".

Boy did I feel silly.
