This little spermatogonial cell started in the seminiferous tubules of the testicle.
Mr. Sperm grew up. He waited at the train station of the testicles called Epididymis
Then, he hopped on the Vans Deferens train to travel to Urethra.
The train made a quick stop at the Seminal Vesicle so the passengers could get some fructose snacks because they were running low on energy.
To get to his final destination faster, Mr. Sperm joined a speedboat called the Prostate Gland that sailed the Bulbourethral Gland Sea
In order to finish his journey, Mr. Sperm had to swim his way through the treacherous waters until he reached the Island of Penis. After a brief visit, he flew off in an airplane, never to be seen again.
