Funny story, that
On the train back from Asakusa, I squeezed into a seat next to a man fat man sprawled haphazardly half on the bench and half on the woman next to him. They were both large, drunk, and exceedingly obnoxious... but of course, I didn't know that until the train started moving and then I was too interested in what they would do to get up.

When I sat down the man (intentionally? unintentionally?) pushed himself rather hard against my shoulder a few times. I pushed back and smelled sake, so I inched away enough to give him his comfort room. Fortunately for me, he didn't feel like badgering a foreigner and seemed mostly to want to go to sleep. Unfortunately for him, the fat, stupid looking woman (his wife? daughter? I dunno) was a rowdy drunk and quite pissed that he would dare go to sleep on her.

Instead of letting him sit quietly, she repeatedly smacked him on the head and in the crotch and asked, at the top of her lugs, "Hey, what stop do we get off? WHAT STOP!!" and if he didn't respond "Shinbashi" for the millionth time, she smacked him more insistently and yelled "Wake up you! WAKE UP!"

After a bit of this, he would grab at her face and repeat the station name (Shinbashi) a few MORE times while smooshing her nose and lips all around. Then she'd scrub at his head with her hand while he made noises somewhere between liking it and wanting her to stop.

This continued until they got off... at Nihonbashi...

Three stops before Shinbashi.

Eh-hurrrrrrrrr....
