Phillip and Gillian, a young couple who had only been married a week, and who were both rather inexperienced in certain matters, paid a visit to their doctor.
“I can’t figure it out doctor, and I’m really worried,” said Phillip. “My testicles are turning blue.”
“That is pretty unusual,” said the doctor. “Let me examine you”.
So, Phillip takes his trousers down, and the doctor takes a look.
Sure enough, Phil’s testicles are a bright shade of blue.
The doctor turns to Gillian. “Are you using the diaphragm that I prescribed?”
“Yes, I am doctor”, she replied.
“And what kind of jelly are you using with it?” he asked her.
