So, does this only apply to girls?

@Goldfritha I feel like I've looked everywhere. There should be a Your Milage May Vary page but I can' find where to create it. @Spam Warrior 3000 YMMV in deciding if Sam is a dumb blonde even though in iWin A Date when Carly is telling Shannon everything Sam still says "Shhh. It could still work."

There were origially two blondes on the "Jeopardy Clue Crew," Sarah Whitcomb and Sofia Lidskog. Now only Sarah remains as the sole blonde there. Neither was dumb, and this troper was lucky enough to be playing "Jeopardy!" as a real-life contestant in February 2002 when they and their two fellow members, Jimmy McGuire and Cheryl Farrell, were in the audience for the show he was taping.

That being said, I had to revise a popular blonde joke (because I knew at least one blonde who was very smart, especially in this troper's field of work):

Q: What are words you will not hear MOST blondes say? A: I'll take "The Dreaded Nuclear Physics Category" for $2,000, Alex.
