Olivia Jaimes has done a couple of gags about it being kinky natural hair, and about Fritzi also having it (and using hair treatments to try to get around it).
Nice! I’ve met her in person a few times and was (a very small) part of an art show at the Cartoon Art Museum in San Francisco thanks to her. I don’t have any physical artifacts from that though, but good memories are nice to have too!
I always appreciate how OJ has such good representation of (possibly undiagnosed) adult ADHD.
