Early in the summer me and my college roomates had a keg party where we gave people name tags (who paid) with goofy/funny names on it. This idea was a huge hit for everyone that attended and had people laughing/talking about for weeks later.

Now that we are planning on throwing another big party I was wondering if anyone had any ideas to make it unique then other random parties. I'm trying to avoid themes though because where I am from most people don't even follow the themes. I was thinking something like glowsticks for each guest and blacklight type thing, but this seems expensive. Any ideas?

I had a party the other week where everyone needed to wear some kind of hat.

Think silly
