Fence!
Scared yet, Mexicans? Yeah, that's right! George W. Bush signed a bill to build a 700 mile fence along our southern border. So, if you try and get into America, there will be a one in three chance you'll encounter... A FENCE!
Do you think you can climb a fence? I don't think you can. Looks like you'll have to hike miles to get around the fence.
Miles.
By the time you get in America, you'll be tired. That's right; sneaking into America will be quite tiresome now.
So, take that, Mexican! We now have a fence!
...or we soon will... when funding gets approved...
