When a doctor gets sick.

When a dentist has a cavity.

When a fireman's house burns down.

When a police officer breaks the law.

When an electrician has no power in his house.

When a professional swimmer drowns.

If a cow is lactose intolerant.

Jumbo shrimp.

If the team mascot didn't like his own team.

If a teacher didn't know the answer.

When a paramedic dies.

When a gardeners plants die.
