I like fun. This could be anything from a baseball game to an impromptu karaoke night to an outdoor concert to checking out an indie art fair. I'm open-minded and like trying new things. The online dating thing is still relatively new to me, but I'm interested in meeting people who actually like to do things besides get wasted, smoke a lot of pot, and watch TV. I'm sick of guys whose best friend is their hair gel and who think buying you a drink in a bar counts as a date. If you think you can handle a lot of sass, contact me.
Addendum: I'm not going to laugh at your jokes if they're not funny or tell you something looks good when it doesn't. If you need a chick who only exists to stroke your ego and look good in a short dress, keep walking. Here's what I'm looking for: someone I can go out with--to concerts, for dinner, for a few drinks--someone I can have a night in with--watching movies, reading, playing board/card games--someone who is capable of intelligent conversation--i.e.; discussing politics, the environment, relationships in general, religion, philosophy, etc.--someone who is curious to know what I do, how my day was, how my family is doing, and who is interesting enough that I also want to know those things about them. Someone I can have an adventure or two with (meaning you're willing to occasionally step outside of your comfort zone and try new things) and many more laughs with.

A good first date for me would be grabbing some drinks somewhere not too loud and just talking. If we don't click, no big deal--we both move on and try again. I think it's almost always worth it to give someone a chance. Plus, drinks are noncommittal. You can walk away at any point if things take a turn for the worse.
