ChrisGendo vs. AshcrementVII was a YouTube Poop Tennis match that took place between September 26 and October 17, 2010. The match was themed around only using animated sources for its duration, and as a result each round features a unique mixture of both Japanese and Western animation, with a particular focus on Disney-related media for the latter. Sources added include Welcome To The NHK("I'M GOING TOWARDS THE LIIIIIIIIIIGHT"), Bakemonogotari, Kara No Kyoukai, the Touhou music video for the IOSYS arrangement of "Heartfelt Nekoromancer", Dragon Ball Z: The Tree of Might, Full Metal Panic!, Ranma 1/2, Urusei Yatsura, Revolutionary Girl Utena, The Great Mouse Detective(1986), DuckTales, Chip n' Dale: Rescue Rangers, the Daffy Duck short Duck Amuck(1953), the Goofy short No Smoking(1951), and the Mickey Mouse short The Band Concert(1935).

It is notable for being AshcrementVII's first ever tennis match, and he made an immediate impression on the tennis community at the time for a unique approach that already seemed fully formed. He and ChrisGendo found each other having incredible chemistry together, and the match was the beginning of a close years-long friendship between them. They would go on to play in many more matches together, both collaborating and volleying off each other in different configurations.

One such match was a rematch in the same volleying order, revisiting many similar themes and ideas. This took place one year after the original match, between October 15, 2011 and October 21, 2012. Alongside the reappearance of sources from the original match, new additions include the Altus puzzle game Catherine(2011), The Melancholy of Haruhi Suzumiya, Great Teacher Onizuka, Neon Genesis Evangelion, Serial Experiments Lain, Hanasaku Iroha, A Goofy Movie(1995), Darkwing Duck, My Little Pony: Friendship Is Magic, Pinky and the Brain, and the Mickey Mouse short Mickey's Trailer(1938).
