I really, really want one of Rouge's Polly Bar Mistress drinks right about now.

Here's mine that I stole from the end of Season 3 of Sex and the City. It's a tricked-up, and more potent, version of a Bellini:

Flirtini

1 shot of vodka
2 shots of Champagne/Sparkling
2 shots of Pineapple Juice

Combine ingredients and either serve over ice in a highball glass, or serve in a Martini glass or Champagne flute.

Be careful with this one though - it's knocked me off of my feet many times even when I've tried to behave.
