A blonde was visiting Washington, DC for the first time. She wanted to see the Capitol building. Unfortunately, she couldn't find it, so she asked a police officer for directions - "Excuse me, officer, how do I get to the Capitol building?" The officer replied, "Wait here at this bus stop for the number 54 bus. It'll take you right there." She thanked the officer and he drives off. Three hours later the police officer returned to the same area and, sure enough, the blonde is still waiting at the same bus stop. The officer got out of his car and said, "Excuse me, but to get to the Capitol building, I said to wait here for the number 54 bus and that was three hours ago! Why are you still waiting?" The blonde replied, "Don't worry, officer, it won't be long now... The 45th bus just went by!"
