About a week after I had mine, I was at half million dollar home to install a satellite dish. I beat the owners home, and met them in the driveway, The husband and his wife got out, I shook their hands and said to the Gentleman, "You look familiar, where do I know you from?"
Turns out he was my Doctor that performed my vasectomy! We had a laugh, and then I said, "Hey I need to bring you in a sample to see if it took, Can we I do that now?",..He laughed, the wife rolled her eyes and went into the house.
I brought in a sample to his office the next week.
