Sometimes height is a matter of confidence.

Today is my birthday! (insert applause here)
The best birthday present I could ask for is for you to simply tell someone you know about Biff. Someone that has never seen him before.

Send an email, post a link on Facebook, Reddit, Stumbleupon or your favorite forum. Open the website on computers in a store or computer lab and stand in front of it laughing and pointing. Get a stack of Biff Xmas cards and send one to everyone you know that likes to softly chuckle at their mail. Write the word “Biff” on your forehead so that people will ask what is wrong with you.

Please, try to refrain from doing anything illegal.
