Banks.

There has been much to-do about banks recently. Indeed these are troubling times, but not if you've entrusted your fortunes to a quality bank like Commerce Bank. (By the way, commerce means: transactions having the objective of supplying commodities. So Commerce Bank could also be known as The Bank That Makes Transactions Which Have The Objective Of Supplying Commodities. Whhheeeeeee!)
I digress.
The Commerce at 14th and 5th has a Penny Arcade (illuminating press release here). Anyone can use the Penny Arcade to count your change and if you guess within $1.99 of what the end count is, you win a prize! Because I rule, I guessed $89.00 before an end count of $89.51. Elated, I went to claim my cash and prize from the teller.
And boy, I'm glad I did because look, I won this piece of shit coin bank cast in the likeness of the "C" in the Commerce Bank logo. Whhheeeeeee!
