For a bit of levity.
You'll have to excuse this one being about someone else's parent, though. The children* of my high school's band teacher also attended the school where he taught, and were initially rather shocked to hear of their father's reputation for being something of a crazy fellow who showed up to his job trashed every so often. Never for a class, but at the year end concerts.

One year, everyone crammed into the auditorium several hours after school to see the school jazz band play. Espo, as he was affectionately called by his students, was on the stage conducting the first song. He just jumped right in with no intro, flailing manically, the song only proceeding normally due to the best musicians being those in the rhythm section. Still, he was known for being odd, so nobody in the audience suspected anything at that point.

After the song had finished, he looked around for a mic to give a little speech. For whatever reason, it had been place on the floor below the stage, about 12 feet out. Undeterred, he calmly strolls over to the side of the stage, turns at the stairs, and then falls right over. He dropped down the stairs and landed in a crumpled heap. A couple moments later, he woke up, dusted off, and continued with his concert.

After that show, his kids stopped trying to refute the stories about their dad being like that.

*Kids may have been invented so that a mildly amusing story fit.
