Does 1 Tortilla Equal 2 Slices of Bread?

Ah, the questions that mankind has pondered since time began:

• If a tree falls in the forest, and no one is there to hear it, does it make a sound?
• What is the sound of one hand clapping?
• Is genetics or environment the stronger factor in determining a person's character?
• Does mankind truly have free will?
  
• How many roads must a man walk down before they call him a man?
• Is a burrito a sandwich?

Thanks to Brian (and thus Rafa) for pointing this out.
