I hate it when a bank assigns me a PIN number for my bank card. I never have a really good way of remembering it apart from writing it on a tiny piece of paper and hiding it in my wallet. It seems like they do this so that I don’t pick something obvious but really it’s much worse.

Remembering my PIN is easy. Changing it to be secure is hard.
Ninja Biff, the master of eating spagetti in a blink of an eye, and vanishing into a bowl of mashed potatoes….what, I can’t come up with something clever.
HAH…
For my phone PIN number, I look on my sim card and use the first 4 numbers!
And then use my phone PIN for everything else, including my Wii Fit Password. (*Not sure WHY I have one of them…*)
