user5779: I'd like to see a video tutorial that explains in detail how to make a paper wallet without paper, AKA, a "memory wallet" -- thx. 

user4241: step 1 - memorize all the private keys that would otherwise be stored in some sort of wallet file
step 2 - there is no step 2 

user3171: You can use http://brainwallet.org to generate a so-called "Memory Wallet". Do not use the live website, download the sourcecode from github.
How this works is you select a phrase, like "Correct Horse Battery Staple", and that phrase will consistently compute to a keypair you can use to store and later retrieve bitcoins.
BE EXTREMELY CAREFUL, or maybe don't do this at all. There are untold numbers of robots perpetually checking the blockchain for any conceivable passphrase. If your passphrase is not EXTREMELY strong, any coins you put in there will likely be swiped in a matter of hours, if not minutes.

If you really want to make a brain wallet, I recommend something absolutely impossible to brute force, like
my favorite superhero, childhood address, my social security number
