Kenny tried to get Spenny to drink the semen he collected, but Spenny refused. Kenny then splashed Spenny with the semen.
In the episode where they had to produce more cum, getting a mouthful of cum for the humiliation was about as related as you can get a humiliation to the episode.
Kenny got semen from other crew members and collected semen from used condoms in alleyways. In addition, Kenny stole an x-ray machine and irradiated Spenny. Just before the final verdict, Spenny filled his beaker with hair conditioner, which fooled Kenny; however, he couldn't go through with cheating and quickly admitted what he had done.

In the Mini-Comps episode, there was a segment where Kenny and Spenny were going to produce semen to prove who was the most virile. In this segment Kenny put a picture of Spenny's grandmother in the room, and Spenny was unable to produce any semen. Jump to the episode titled, "Who Can Produce More Semen?" and the whole episode acts as a humiliation pointing back to the mini-comps segment, where Kenny was clearly taunting Spenny at not being able to produce a drop of cum. The fact remains, it will go down in recorded history, Spenny was unable to produce any semen in either the mini-comps segment or the whole semen episode.
