When topping a pint of Guinness this St. Patrick's Day, bartenders of the highest caliber will pour beer into a glass, leaving four inches from the top. It is said they wait 119.5 seconds, then exact the "top up," adding the Shamrock on the head, and waiting another 119.5 seconds for the vicar's collar: one inch of head. That's a perfect pint!
