a) The most delicious snack food ever. It's especially great for parties! It's very simple to prepare as well. All you need to do is:

1) Buy a bag of pretzels.
2) Set them down at the party long enough to have played a few rounds of your favorite drinking game.
3) Open the bag of pretzels and begin to eat them, after a set amount of time one of your drunken friends will knock them from your hands and THERE YOU HAVE IT! Delicious Floor Pretzels!

b) A bitch to clean up in the morning... you may even need foot brooms
