Take a Drink: every time you wonder why they couldn’t get a better wig for Christina (her ‘stage wigs’ looked more natural than that sisterwife-looking thing on her head throughout the movie.)
Take a Drink: whenever there is a reaction shot of someone being surprised/blown away by Ali’s (Aguilera) incredible voice.
Take a Drink: whenever you see the token (and apparently mute) black member of the Burlesque troupe.
Do a Shot (of PATRON!): whenever someone refuses to let Kristen Bell’s lush character have a drink (she can’t, but you can!).
