Drinking Game: Make It Stop

Everybody loves to sing: We sing along when we hear our favorite song on the radio, awkwardly hum to our I-pods on the subway, and drunkenly recitate Top-20 songs during karaoke. Most of us, however, are not very good at singing.
When people drink they almost assuredly sing. Something about the combination of warm beer and lowered inhibitions makes people want to display their mediocrity to the world. Yes its fun to gallivant about on stage. And yes, a couple fortunate souls are blessed with magic vocal cords.
But the majority of us sitting timidly by the bar are not interested in listening to a butchered Pop song.
This is why drinking becomes an imperative when going out to an event such as karaoke, hanging out with friends or family members, or attending a mandated work event. Sooner or later some idiot is going to try to sing a generic song and some other idiot will follow his or her lead. And so, you might as well have fun with the ensuing cacophony of shitty vocalists.

The Rules:
(1) Drink every time someone misremembers a lyric (e.g. "Spaceships are meant to fly").
(2) Drink every time someone pretends to sing the lyrics, but actually has forgotten (e.g. "hanniandsaidajs fly).
(3) Drink every time someone has forgotten the words and thinks inserting original lyrics will be so hilarious (e.g. I'm so cool and maybe high)
(4) Drink every time someone only sings the chorus (e.g. starships are meant to fly).
(5) Drink every time someone overemphasizes a word in the song (e.g. fly).
(6) Drink every time someone says: "I love this song!"
