Surprise Party

Hello Ladies,

Does anyone have a cute poem or wording for a surprise party? I am throwing a 50th for my mom and want to start on the invitations.

Thanks

Here are a few:

In case you didn't know,
(Name) is turning the big 5-0!
We're having a party and she doesn't have a clue,
there'll be food, drinks and dessert
so all we need is you!

There's a Birthday Party
and you are invited to show
But don't tell (Name)
because HE/SHE doesn't know
So if you can make it
here's a word to the wise
make sure you come early
'cause it's a surprise!
