Passwords

My office uses US Bank for banking. I really don't like them because their business online banking sucks. It's hard to navigate. I can't look at any transactions, I have to compile a report. AND they require me to change my password once a month. So today I was asked to change my password and I attempted to change it to:

lame1234

They wouldn't allow me to use this password because I had recently used it. Go figure.
