Okay, I'm halfway through making them, here's what I have so far:

They're expecting a baby,
A bundle of joy
A very special gift,
Is it a girl or a boy?

Men are quite welcome
You can play the games too
It’s also a housewarming
So the decision’s up to you

Baby Shower & Housewarming Party for
Tenielle & Scott

at their new house
{Address}
RSVP by March 1st
Following along the same poem theme, how can I add in that I'll be doing my World's Greatest Shave then? I've tried wording it a few different ways but it's making it a bit awkward...
