I was at web developer training, which was in a big open space underneath some other structure. This was a metaphor; they were trying to teach 'foundational' software engineering concepts, like properly layering abstractions and not making a huge fucking mess.

I had one of those medium-sized cardboard containers of ice cream with me. On the carton was playing a video of Dianne Hess, as if she was a character in a sitcom (I was probably thinking of Roseanne), and I said "aww, fukkin JoAnn" (all three names end with "ann", and I guess that's the part my subconscious latched onto).

I started scooping myself a scoop if the ice cream, which was getting a little melty already, but then dropped it on the floor, and said "Fuck!"

Something seemed really funny about "Aww, fukkin Joann" followed immediately by "Fuck!", and I woke up laughing about it.
