An American is traveling around London in a cab.
They drive past the Westminster Palace. “What building is this and how long did it take build?” Asks the American. “This is the Westminster Palace and it took 30 or so years” “That’s way too long. In America we would’ve built it in under 3 years”
They drive past the St James Palace. The American asks the same question. “This is St James Palace and it took 4 or 5 years to build” “That’s still a lot. In America we would’ve built it in 4 or 5 months”
They drive by the Gherkin. The American asks his question. Annoyed the driver answers:
“I don’t know, it wasn’t here this morning”
