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 Westminister Abbey the cabbie was silent.

"Whoah!  What's that over there?" asked the Texan.

Replies the cabbie, scratching his head. . . .

 . . . "Now that, I don't know; it sure wasn't there yesterday!"
