Out,
of all the sperm I just released,
who would win, them or you?,
Well if they were to go straight for the egg,
they might cause me a little trouble,
but would you lose?,
Nah,
I'd win.

While the sperm was on his way to the uterus,
woman opened her domain, the immune system,
and cells from woman's body started slaughtering millions of sperm cells,
luckily for man's favorite sperm.

It learned domain amplification and nullified the immune system's sure-hit effect.

After a hard-fought battle,
the sperm finally entered the egg.

The egg asked the sperm,
are you the strongest because you're the first sperm here,
or are you the first sperm here because you are the strongest?,
The sperm replied, when it comes to conception,
we are the exception,
because throughout ejaculation and impregnation,
I alone am the born one.
