I took a gf out to lunch one day, to a local Japanese restaurant. Yakitori was their house special, but they'd just started serving sushi (this was back when sushi was just becoming popular). She ordered sushi, I had the yakitori. She went on and on while we ate, talking about how she used to live in Japan, how sushi was good for you, etc. etc. She ate everything on the plate, leaving a little green lump for last. It was about the size of the last joint on my little finger. She picked it up, popped it in her mouth, chewed a couple of times, then swallowed it. I knew what it was, but kept my mouth shut--she obviously knew what she was doing, after her talking up the sushi... I just sat and smiled, watching her. After a few seconds, her face turned red, then out ballooned her cheeks and eyes, just like in cartoons. She jumped up and ran for the ladies' room. I waited until the door was closed before I laughed. I guess it was worth paying for our meal, considering she didn't keep it down very long.
