As a person who was white-blonde as a child and just plain blonde later, I had to listen to people equate blonde with the idiot gene. Don't think the jokes are funny. Just insert Black, Asian, tall, skinny, blind, deaf, deformed, autistic, dyslexic, or gay into the space where blonde sits and the jokes and stories simply insult and ridicule another group.
Why do this? Blond 101 sounds terrible to me. What an awful idea.
When the butt of the joke or story is a particular group and the deficiency is something of which there is no choice, the result is caustic and more than uncomfortable. It is certainly akin to racism.
Doing this will say a lot more about your personal ethical standards than it will about blonde people
