Uhm...are these paper greeting cards?
Indeed they are! Mustache Wisdom is based on Mustache Party -- an innovative greeting card line from American Greetings that features music and mustache-powered motion. Basically, each card has a furry mustache on the front that springs to life and sings a one-of-a-kind song. They're funny. You should buy them.
How do I thank you?
Your happiness is thanks enough.
