Does "Sonic" Truly Exist?

In the midst of all the craziness surrounding the "Lost" finale yesterday, I began thinking about the modern mysteries surrounding my life.

I'm fairly certain that Sonic does not exist at fucking all. No fast-food place can have such great and consistent deals without any locations. I can't believe you guys have that 4 double-cheeseburger for $2 deal without any known locations in the northeast, south, west, or midwest. Plus they allegedly have people that roller-skate your food to your car. That shit doesn't happen. This isn't "Grease." There are pebbles on the ground that will most definitely send that small coke and those tots flying.

Until I actually see one with my own eyes, I will equate Sonic to "The Island" on Lost. A place where nothing is explained and it probably doesn't exist.
