A blonde got tired of blonde jokes...

[Seafood]

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 of the state capitals."
One of the guys, of course, said, "I don't believe you. What is the capital of Nevada?"
"N," she answered.
