Saki Sanobashi, often paired with the subtitle Go For a Punch, is a possibly fictional OVA from the 1980s. According to rumor, the OVA is thirty minutes long and features anywhere from three to nine high school girls trapped in a bathroom with no doors or windows, who eventually all commit suicide in a gruesome manner.

The anime was first spoken of in a 4chan post ◊ from 2015, and has since been covered by the likes of Whang on YouTube . A subreddit dedicated to researching and attempting to find the lost anime was made in 2019. A person claiming to be the original 4chan poster later visited the subreddit claiming that they fabricated the story about Saki Sanobashi in a matter of minutes as a joke, but the lack of any definitive means of verifying that they were indeed the original poster means that the OVA's existence is still very much up in the air depending on who you ask. If it is fake, it'd certainly beat out Ichiban no Tempura as the most memorable fake anime not related to Dragon Ball Z.
