Probably

A blonde woman was sick and tired of all the unfair jokes about blondes. 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 the 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 Texas?" "T!" she answered.
