Glitter-encrusted Shamrocks

Sherlock, John and Rosie celebrate St. Patrick's Day with face-painting and glitter-encrusted Shamrocks. Later in the day there is whiskey and, ahem, trouser snakes.

"John removes his finger, making Sherlock pout in protest and dips it into the golden whiskey again. This time, he allows it to drip from his finger down Sherlock’s chest, over the jut of his collarbone and trickle down between the pectoral muscles."
