The possibility, however remote, exists that you will randomly select a sequence with patterns and order. In cryptography, we define the term 'pseudorandom' in order to discuss a class of functions that look random.
Pseudorandom sequences are sequences where, given the first n bytes of the sequence, an adversary cannot guess the n+1th byte with probability significantly higher than 1/2.
Basically, it's important to distinguish between blindly selecting a sequence out of all possible sequences, and finding a particular sequence with no discernible internal order.
I used to have a version of that Dilbert comic as a forum signature for a while, except I hacked a little PHP script so it would insert a random number instead of "nine" into that panel (still repeated), different on every reload. Just to confuse people :)
