An off-road vehicle drives through the desert
stall due to engine failure.
If a white horse comes running, look under the hood and repair the damage.
The driver looks at the horse in disbelief.
After the car was running again, the man immediately drove to the nearest oasis, rushed into the nearest bar and told the innkeeper the incident.
The innkeeper: "You're lucky, there's a black horse running around, but he doesn't know anything about cars."
