description  = """\
Use this program to spongebob-mockify a series of text. Simply feed in a series of words
in the argv (also can pipe words to this, but not enter them interactively through the TTY).
This is done using a random number generator to determine what letters we should capitalize,
with some logic to know that if the last letter was capitalized the previous letter should have
a lower probability of being capitalized.

Also prints ASCII-art of the meme just for posterity and to appease the normies.
