Quickie: Human resistant passwords

Today a random conversation popped up.  How do you make human being resistant passwords?  i.e. passwords that are difficult for a human being to read to another human being?  Length is an obvious answer, as a crushingly long password can exceed human memory buffers.  What else?  How about high ASCII or Unicode characters?

I arbitrarily restricted myself to a US keyboard and 15 character length.  using Here's what I came up with.

Dyslexia Passwords: 

Font Abuse Passwords:

"Evil" Passwords:

That last one is my favorite.  You can write it up on a dry erase board and it looks like a bunch of commas.  Evil.
