A Texan was taking a taxi tour of London and was in a hurry. As they went by the Tower of London the cabbie explained what it was and that construction of it started in 1346 and was completed in 1412.
The Texan replied, "Shoot, a little ol' tower like that? In Houston we'd have that thing up in two weeks!"
Next they passed the House of Parliament - started in 1544 and completed in 1618.
"Well boy, we put up a bigger one than that in Dallas and it only took a year!"
As they passed Westminster Abbey the cabbie was silent. "Whoah! What's that over there?" asked the Texan
Cabbie: "I don't know, it wasn't there yesterday."
