Goat!

Akpos was driving up a steep, narrow mountain road. A girl was driving down the same road. As they passed each other, the girl leaned out the window and shouted,
"Goat!"

Akpos immediately leaned out of his window and replied, "Fool!"

They each continue on their way, and as Akpos rounds the next corner he slammed into a goat in the middle of the road!
