50th Funny Birthday Party Invitation Wording Invitation Wording For A 50th Birthday Party?

Invitation wording for a 50th birthday party? - 50th funny birthday party invitation wording

My husband and I are both 50 years this year. We are an outdoor dinner party in the (live band, BBQ, outdoor cinema, etc.) Can someone help me with the text of the invitation? Something funny? The "everything" I want is to bring their chairs. There are approximately 75 participants - mainly adults, a few children.

You must also help determine how much alcohol on hand. I buy probably 2 barrels of light beer. I have a Margarita machine. Ideas?
