read the signs

A police officer pulled over two nuns riding on a motorcycle, and said to the rider, 'Ma'am, you're driving much too slowly, could you please drive faster?"

And the nun says, 'Oh, I saw the sign with the "21" and assumed the speed limit was 21 km/h"

The officer explains: 'No ma'am, the speed limit is 80. The highway number is Interstate 21."

Then the police officer look at the passenger and see the other nun shaking like a leaf.

"Excuse me sister, but what's wrong with your passenger?"

"Oh, that's probably because we just got off Highway 205."
