"2 Presidents" joke

President Musharraf went to the US & had a meeting with President Bush. Bush said, "I want to show you the advancement in technology in USA. Come with me."
Bush takes him in a deep forest and says, "Dig the ground."
Musharraf digs.
Bush says, "More, more, more..."
Musharraf has now reached 100 feet.
Bush says, "So now, did you find anything?"
Musharraf, "I got a wire!"
Bush says, "You see, it shows that even 200 years ago we used to have telephones!"
Musharraf was very frustrated and he invited Bush to Pakistan. In Pakistan Musharraf says, "Now I want to show you the advancement in Pakistan!"
He takes Bush to a forest and asks him to dig.
After some time Musharraf says, "More.... More... more!"
Bush has now reached almost 400 feet.
Musharraf says, "Find anything?"
Bush tries but finds nothing, "Nothing here!"
Musharraf says, "You see! 400 years ago we had WIRELESS telephones!"
