How to mindfuck a group of strangers

So this came up while I was talking about nonsense with my housemate. Here's what to do to mindfuck a group of strangers:

STEP 1:
Have a friend dress up in cosplay/visual kei/anything weird. It can be anything you like, for example:

 Amane Misa - Death Note

 Mana-sama

Yuna - Final Fantasy

or

.

.

Pedobear!

No, don't go as Pedobear... really...

STEP 2:
All dolled up? Now go to a public place, preferably a coffee shop where there are alot of people. Order 2 cups of coffee for yourselves and just chat normally. IMPORTANT: the one in cosplay should not be the one ordering and he/she should not touch their drink.

 Green & Co in Leederville, Perth would be a perfect place for this setup.

STEP 3:
After about 15-20 minutes, everyone in that area should've noticed both of you. Look at your friend and say:

"I wish you were real so everyone can see you!"

There you go, how to mindfuck a group of strangers =P

VERY IMPORTANT NOTES:
Don't laugh after STEP 3.
For extra dramatic scene, start crying and running out of the restaurant leaving your "friend" behind.
