Cadbury Sperm

My degree is in Biology.
I chose that field because I wanted to find the answers to all the mysteries in life.
So, when I received a basket full of Cadbury eggs for Easter, I wondered where all the Cadbury sperm were.
Did Mr. Cadbury have a vasectomy? Or is he sterile?
Maybe he was diagnosed with prostate cancer, and he had them frozen in a sperm bank before the radiation treatment.
But then, at least they’d be in the freezer section, right?
I asked my grocer where the Cadbury sperm were, and he threw me out of the store.
