Opinions on blonde jokes good or bad?

opinion 1: They are funny but some can hurt people (blondes) I'm a blonde and i enjoy hearing them opinion 2: They can be very mean. Who knows, there might be a blonde out there smarter than Einstein. My hair is brown, with a bit of red, but I have some blonde parts in my hair (and my guy friend made a very good point of that at the dance when my friends were trying to set me up with someone and he asked a guy "Dude, will you dance with her?" and the guy was actually my other guy friend and said, "No" he then asked "Why not? She's blonde!" And automatically screamed, "Hey, I'm smart!" for obvious reasons and I am smart, so he asked my best friend how smart I was and when she said, "Yes" he's like, "Oh, sorry."). Anywho, I laugh my heart and soul out at blonde jokes. It's not as if they're meant to be mean, they're supposed to make people laugh so hard they wet themselves.
