Why is it called a "hot water heater" when you don't need to heat hot water?

Why do doctors practice medicine? Shouldn't they know what they're doing?

Why is a person who plays the piano called a pianist but the person who drives a race car NOT called a racist?

Why does McDonald's put out signs that say picture menus are available... if you can't read the menu how are you gonna read the sign?

No financial institution will loan you money until you have a good credit rating... but you can't establish credit until you pay back a loan.... how's that work?

Ok... I think I'm outta questions for now. Maybe someday I'll understand things.
