Cookies are bakin'. Just read this on slashdot:

Actually if you ignore a (different) bit in ASCII, A-Z is still the same as a-z. (ignore the bit 0x20, which amusingly enough is a space in ASCII, which extra amusingly is 40 in octal while 40 in hex is a space in EBCDIC, which is only amusing if you're amused by ASCII and EBCDIC)

heh.
