I normally go "what the fuck did I even do yesterday?" five minutes before daily standup and look at my git commits and calendar for the day before to piece together a plausible version of my workday (I do my timesheets the same way as well btw). Very little serious information gets passed on but somehow it makes my boss happy and he has told me that he likes the way I do standups.

I work at a small company where most projects only have one or two developers so standup meetings are usually a lot of completely irrelevant information. It's very boring. "Yesterday I worked on the thing on the project you barely know what does."
