Thus, this shall be called "What, another forum game?" because the real name: "Alternatives, should you not like pina coladas or getting caught in the rain" is too long. XD
This is a list Esther and I started; let's see what you guys can add.
1. Manhattans, and falling into a creek.
2. Mai Tais and stumbling into a puddle. A very large puddle. A Lake Michigan-sized puddle.
3. Screwdrivers and standing under a sprinkler.
4. Brandy Alexanders and visiting Niagra Falls. Ooh, who is going to have to pee first? XD
5. Black Russians and having Winnie the Pooh, covered in black mud and tied to a balloon, floating above your head for a while.
6. Bloody Marys and naked snow angels.
7. Singapore Slings, and your ceiling leaking because the upstairs apartment's pipe burst.
8. Mint Juleps and tests while hungover.
9. Dr. Peppers (the alcoholic variety) and playing old Simon and Garfunkel albums on a record player.
10. Sangrias and drunken kisses (sans beer goggles).
11. Martinis and making slightly-xkcd-ripoff comics, only with an oboe flavour.
12. Fuzzy Navels and dancing to David Bowie.
13. Tequila Sunrises and long walks through a damp park.
14. Daiquiris and calculus.
15. Gin and Tonics and Robert Heinlein.
16. Snakebites and philosophical discussions. Perhaps even a dash of existentialism.
17. Pan-Galactic Gargle Blasters and thinking about the maximum number of magnets I could fit on my fridge.
That's where we left off, since we both ran out of drink names. I was going to do the Pan-Galactic Gargle Blaster as my next one, but she beat me to it.
EDIT: And no repeats of either the drink or the action!
