Red and Philips father; connection?

[WindexGlow]

Money was tight before red was in the mine.
He saw a sperm bank one day.
He decided to get the extra money.
So he donates alittle. The stuff is forgotten in the back of a vault, but preserved.
Philip's mother wants to have a child. She goes to the sperm bank.
You do the rest.

Proof that red is philip's father.
