Here's a quick true story/blonde joke - (my wife's a blonde, as is my daughter, so I get to tell these jokes and stories).
My wife and I were in a small jewelry store, shopping for a new watch.  We were looking at several different models and taking our time when a two blondes walked in with a small bag of jewelry.  The outfits, makeup, and hair fit the blonde joke stereotype (like, totally).  Since the place was so small, we couldn't help but overhear their conversation with the jeweler, that went like this;
Jeweler:  Can I help you?
Blondes:  Yeah.... we were hoping you could, like, look at this jewelry
Jeweler:  You mean give you an appraisal?
Blondes:  Yeah, we like, want to know what it's worth
Jeweler:  OK, no problem - where did you get the jewelry?
Blondes:  From our great aunt
Jeweler:  Oh, did she pass away?
Blondes:  Yeah kinda
Jeweler:  (Speechless).
My wife and are still laughing about it...and wondering what "Kinda Passed Away" means
