Stick your hand in a Shamrock Shake from McDonald's and then giving your girlfriend the shocker with the shake fresh on your fingers. Yum.
Dad: I just gave my mom The Dirty Leprechaun . It made for a tasty treat.
Son: Wow dad, you sure are swell.

In the month of March when you go to McDonald’s if you want to add chocolate to your mint shake ask for a Dirty Leprechaun.
McDonald’s Employee: What will you like today?
Vincent: A Dirty Leprechaun
McDonald’s Employee: A what?!
Vincent: A Dirty Leprechaun
