A common outcome of a Crash into Hello involves both parties lying on the floor stacked one on top of the other, in the same position they'd be in if they were extremely passionate about one another. Almost always leads to a Not What It Looks Like moment.
After a beat, the two will instantly teleport to a seiza (sitting on knees) position, facing away from one another and blushing furiously. If they can talk to one another, they'll either stammer furiously, or one will berate the other.
- An innuendo-free version occurs in Azumanga Daioh, when Chiyo walks in on Sakaki playing with her cat Maaya. Nothing naughty, just... undignified.
- Subversion: Keiko in Cheeky Angel takes advantage of being pinned under Fujiki to scream and accuse him of being a pervert, in order to knock Megumi down a peg.
- Played with in FLCL, where Haruko goes into seiza after hitting Naota, then starts rolling and moving around jerkily... while still seated in the seiza position.
- Kashimashi: Girl Meets Girl
- Love Hina — most notably when Naru and Keitaro are hitchhiking with Mutsumi while escorting her home, riding in the back of a truck.
- Erio and Caro do one after their Crash into Hello in Magical Girl Lyrical Nanoha StrikerS, though they were facing each other and only Erio was blushing and stammering, and even then for just a few seconds. It seems the kids are too young to be fully affected by the embarrassing situation.
- Mahoraba - Both Kozue and Shiratori are very prone to this.
- Ranma ½
- Skip Beat! - Kyouko is prone to doing this, though does it more because she's truly sorry for something. Interestingly enough, she seems to do this to Ren quite often.
- In Sumomo Mo Momo Mo, Momoko and Iroha pull this move when Koushi catches them rehearsing a confession to him. A pretty intense confession...
- Occurs in Zone of the Enders: Delores, i... between two sentient Humongous Mecha, after a bump puts one's head in the other's lap.
- In the Danganronpa: The Animation anime, Naegi pulls a quick seiza when he wakes up to find his crush Maizono watching over him. It's a rare case of the anime getting to do something the game really couldn't.
- Sort of happens in Resident Evil 6. Jake pushes Sherry over to protect her, lying on top of her, before a stream of bullets enter their cabin. She doesn't realize at first.
