> I once blew up when multiple people said that they were in [the scrum] meetings the day before; this is an example of saying things to account for your time

Have you considered the possibility that your temperament or personality might be the reason that multiple people on your team feel they have to pre-emptively justify themselves to avoid angry criticism? A meeting where people have to stand in front of their peers and potentially admit their failings can be quite anxiety-inducing if team members can't be trusted to respond in a professional manner.

"blew up" and "rant" implied more than intended; The team reacted really positively to the feedback and adjusted accordingly; The team became really healthy at preemptively pairing and parallelizing work, but - to your point adding personalized fun to the standup.
