Things That Make Ya Go "Hmmmmmmm"

OK Guys/Gals here is a little humor for the board.
This is about all those things that made ya go "hmmmm"
(started by Arsenio Hall).
Please feel free to add to this.

Why do you drive on a Parkway and park in a Driveway?

If they are "Apartments" why are they built next to each other?

Where does the white go when snow melts?

If "Loco" means crazy in the spanish launguage - does
Locomotive literally mean "Crazy Train"?

Who was the first person brave enough to eat an Oyster?

Where do old Garbage Trucks go once they are useless - since you never see any in junkyards?

How do they print the "MM" on M&M's?

Anyone else?
