Need Visa joke for kids

A senior Senator called and had a question about the documents he needed in order to fly to China.

After a lengthy discussion about passports, I reminded him that he needed a visa. "Oh, no I don't. I've been to China many times and never had to have one of those."

I double checked and sure enough, his stay required a visa. When I told him this he said, "Look, I've been to China four times and every time they have accepted my American Express!"
