I'm a fun dad, but I don't know if I'm the fun, crazy dad.
My father is Italian, and I never met my paternal grandparents. The family name was 'Caroselli' and it was changed in the mid '50s. I think they wanted to assimilate, which was pretty common, although I love the name 'Caroselli.'
I play the baritone horn - which is like a mini tuba, and is the least sexy instrument you can choose, and I generally say I don't play one so I don't have to acknowledge it. I also play fife.
I don't think my kids have to worry too much about me embarrassing them because that's not how I would want to grow up, with wacky dad showing up at school and performing for everyone.
