DMC: I beg to differ. Burritos are pretty much the same thing as soft tacos.
Mexican popular tradition tells the story of a man named Juan Mendez who used to sell tacos in a street stand, using a donkey as a transport for himself and the food, during the Mexican Revolution period (1910-1921) in the Bella Vista neighborhood in Ciudad Juárez, Chihuahua. To keep the food warm, Juan had the idea of wrapping the food placed in a large home made flour tortilla inside individual napkins. He had a lot of success, and consumers came from other places around the Mexican border looking for the "food of the Burrito," the word they eventually adopted as the name for these large tacos.
TheRealTJ: All the burritos I've seen have had lettuce :P2
In the United States, however, fillings generally include a combination of ingredients such as Mexican rice, beans, lettuce, salsa, meat, guacamole, cheese, and sour cream
EDIT: Proofish :D
Actually, Atlas is holding the heavens on his shoulders, but whatever.
Hmm... Doing a handstand can be seen as lifting the world if you look at it upside down, so my answer has got to be being lifted by the world, because it makes no sense in this context.
... here is a picture to explain it for you.
