Well, there was this blonde who just got sick and tired of all the blonde jokes. So one evening she went home and memorized all the state capitals.
Back in the office the next day, some guy started telling a dumb blonde joke. She interrupted him with a shrill announcement,
"I've had it up to here with these blonde jokes. I want you to know that this blonde went home last night and did something probably none of you could do...I memorized all the state capitals."
One of the guys, of course, said "I don't believe you. What is the capital of Nevada?"
"N", she answered.
