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!

Silver Shamrock 

Fictitious mask company in the third instalment in the Hallowe'en franchise, "Season of the Witch" (the one without Mr. Myers). The masks are the colours of the Irish national flag (orange Jack-O-Lantern, white skull, green witch), and are made by a company in a weird all-Oirish town on the coast of California. On activation by a signal on the big night, the masks transform their (numerous) wearers' heads into so many divers creepy-crawlies. The Silver Shamrock company wins the booby prize for the most irritating television jingle ever inflicted on the world in fact or fiction; a countdown to the tune of "London Bridge is Falling Down", starting "(x) days to Hallowe'en, Hallowe'en, Hallowe'en". I had it in my head for WEEKS. The head of the company is played by an actor from Wexford, Ireland, and incidentally as far as I can tell is the only figure in the history of American horror films to pronounce Samhain correctly.

Four days left to Hallowe'en,
Hallowe'en, Hallowe'en,
Four more days to Hallowe'en,
Silver Shamrock!

One time I slipped a girl the shocker and she retaliated by sharting. It was an all out Sharcker!
