How can you not love Canadian money? Its plastic, which make it ultra hard to rip or destroy, it's colored, which make it easy to count and see what bill is how much. It's also really hard to fake them.
How?
Americans were conditioned by playing Monopoly to think that colored money = play money, or toy money. And everyone knows "it looks like a toy" = "it looks cheap". Ergo, Canadian money is the one that looks cheap.
