In the 1970s, a bunch of us would have marathon sessions playing this newfangled game called "Dungeons and Dragons." It was a box set then, AD&D was yet to come. We played in a games club on Yonge Street in Toronto, and just down the street as the kind of sleazy movie theatre that played "Swedish Naturist" movies and any other porn or porn-adjacent films they could get away with.

On Saturdays, we would play until about 11:45, lock the club up, and go to the theatre, where they would show The Rocky Horror Picture Show at midnight. It was semi-wild. A few people would be there in costume, and lots of people would shout out the most famous lines.

I enjoyed it, and ended up making a minor contribution to the atmosphere: I started brining a water pistol along, and when there was rain in the movie, I'd fire it upwards, waving it randomly so other patrons would get a little sprinkle.

People liked that kind of thing!
