Need Help for a Surprise Birthday Party!

Planning a surprise 50th birthday party for my mom and have

about 80 people getting together at a resturant and she has no

clue. I know I will have to go up and present a speech

and need some ideas and tips on what to I need to say & cover

with a side note of making it short, sweet and a bit humorours.

Anybody feel free to chip in with some thoughts. I will keep

everyone posted on how it

goes.
