Okay, I'm "invited" to a baby shower Friday night (05.23.2008) with my new lady.

What's the use of a man at a function such as this? I've never been to something like a baby shower; I mean, I always thought this event was the realm of the XX chromosomes.
I know most all the people expected at the party; hell, my girlfriend is most of 'ems supervisor. Most of these women I work very closely with...
Here's what I'm thinking I can do:
a) I know food will be served. I figure I'll "man" the grill. I spent two decades in a firehouse. I can cook; I've never seen an anorexic fireman...
b) the "dad-to-be" is attending; I can offer him some man support.
c) beer will be on hand. I can cook on the grill, support the dad, and drink lots of cold, frothy, adult beverages.
What am I about to get into??
