In the vein of "That's what she said," 'sperm joke' is also one of the most versatile jokes on Earth - and can be used in response to nearly anything. Shouting "Sperm joke!" makes the conversation infinitely better - and turns the subject of the phrase into a comedian! To be used especially after any conjugation of the verb "come."
A: I didn't know Mary was coming to town!
B: ... Sperm joke!

A: Are you going to come over or not?
B: ... Sperm joke!

A joke involving sperm and 2 people (preferably opposite sex/gender)
A man and a woman meet in an elevator. "Where are you heading today?" the man asks.
"I'm going down to give blood."
"How much do you get paid for giving blood?"
"About $20."
"Wow," says the man, "I'm going up to donate sperm, and the sperm bank pays $100." The woman angrily gets off the elevator.
The next day, the man and woman meet in the elevator again.
"Fancy meeting you again. Where you off to today?"
"Sperm bank," she says with her mouth full. Thats a sperm joke
