baby showers!

KL
I want a baby shower that's actually fun to attend. I've only been to one such affair before so I'm not sure what I should do with planning mine. (The one I'm referring to was a co-ed party they invited liken 150 people to. There was a big BBQ, a beer wagon full of kegs, and minimal games). 
Yes, it's about the baby, but I don't want it to be all baby all afternoon. 
What were highlights of baby showers you had or attended? What would you stay away from?
