Dear Plunge (readers)

I will be getting married to an AWESOME babe next year and we are currently in planning mode. She is somewhat traditional, but not fully and i can trust her fully to make this day super awesome.
Now, amongst my friends and family i am well known for... shenanigans.
(Insight in my personality http://itkilledmycat.blogspot.com )

For my wedding, i just want to incorporate a subtle "Dave Touch".
First i suggested a beautiful wedding cake, but with a hand sticking out of the top... but that got veto'd.

Now i DID convince my Wife-To-Be to let me cut the wedding cake with a katana, but i want to add a few tiny things that people will go... OMG that is SO Dave & Julia without ruining the overall, Julia induced cuteness.

The best thing would be that people don't even notice it until they watch their pictures and go...WTF...is that a Ninja in the kitchen?

Stuff like that!

Could use ideas!
