A blonde was visiting Washington, DC. This was her first time to the city, so she wanted to see the Capitol Building. Unfortunately, she couldn't find it, so she asked a police officer for directions.
"Excuse me, officer," the blonde said, "how do I get to the Capitol Building?"
The officer said, "Wait here at this bus stop for the number 54 bus. It'll take you right there."
The blonde thanked the officer and he drove off.
Three hours later the police officer came back to the same area, and sure enough, the blonde was 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. That was three hours ago. Why are you still waiting?"
The blonde said, "Don't worry, officer, it won't be long now. The 45th bus just went by!"
