Take shot…
…if Shannon (Maggie Grace) shows up. Take another if she’s wearing a mini skirt. …every time Ben shoots someone. …any time someone speaks Latin. …if Desmond and Penny (and baby Charlie) are reunited. …if Faraday and David are both playing at that concert everyone in sideways world seems to be going to.
Chug…
…every time Jack reminds everyone that he is in charge. …if Claire goes into labor in sideways world. …if Juliet is David’s mom. …if you hear Mr. Eko’s name. …if anyone mentions the polar bear.
Finish your drink…
…if Vincent re-appears. …if (fingers crossed) Kate dies. …if (the real) John Locke is resurrected on the island. …if Drive Shaft performs. Or that damn “You All Everybody” song is played.
