thought of the day 2009 08 01 - Banks

So I was in Chicago for a few days and I keep walking past these ATMs for Fifth Third bank. This has me deeply disturbed. I know bank's can't count, but I figured at least they could be grammatically correct. I could understand Fifth & Third, perhaps if the bank was first established at the intersection of Fifth Ave. and 3'rd St. But to have the FIFTH Third bank means that there were four Third banks before this one and that would just be confusing. I'm almost tempted to open an account just to be able to ask a branch manager if they have better interest rates than the Third Third bank or the Fourth Second Bank.
