Shamrock Shake 

The best possible item ever placed on the Mcdonalds' menu. People wait hours just to buy one when they start selling them the month before St Patrick's day. A green vanilla mike shake (which may or may not be more addictive than crack.)

Person X: What the hell is this line for at McDonalds?
Person Y: They released Shamrock Shakes, again!
Person X: Is that a Mexican thing?
Person Y: Irish.
Person X: Ahhhh...bless the Irish and their dairy treats!
