Separated by character
- Prepare to take a shot each time the anime shoehorns fanservice into any scene, especially during season 2 and the OVA episodes.
- And another for whenever the camera (or the other characters) call attention to the gargantuan size of Ms. Aki's breasts.
- Take a swig every time he "accidentally" grabs a girl's breast, or pulls down their skirt, or somehow ends up in a compromising position with them.
- Take two if the girl is either Haruko, or Himegami.
- Take another each time they punish him for it.
- Take one extra if Usui is also involved.
- Take a shot each time he gets a nosebleed.
- Take a swig each time she denies being in love with Takeru.
- Tip one back whenever anyone notes that her breasts seem to have gotten bigger.
- If reading the manga, take a shot for each upskirt panel of her panties.
- If watching the anime, take two if it's zoomed in on her camel toenote .
- Knock one back every time someone makes a comment about how small her breasts are.
- Take one sip each time she either grinds her foot in Takeru's face, or stomps on him.
- One for each time you see her in her lingerie, or trying on new ones.
- Take one for each time he sparkles, or poses.
- Add another if he does either one while flashing a Twinkle Smile.
