So my sister is getting married tomorrow and I want to have some fun. I'm obviously going to be respectful towards her and her special day, but how do I go about picking someone up?

I'm 19 so most here are older. I know it's possible I just dont have a whole lot of experience.

Any tips would be appreciated. My uncle challenged me to pick up this one chick but I think shes interested in my older brother --a groomsman said he wouldnt try as shes not worth it.

My uncle is throwing a party (they're Californians and party a lot --were from northern Idaho and arent as wild) tomorrow night so I might have a shot there too.

Thanks in advance.
