Ssssh, I've been getting away with kissing for years.

IIRC, offline mode is only good for a limited amount of time (ie. 30 days). If you don't connect to Steam after that time period, you lose the ability to use offline mode. Also you have to actually be online to activate it (makes a lot of sense, huh?), so if your internet connection goes out or the Steam servers are unreachable, you're SOL. Say goodbye to your games.

Offline mode works indefinitely, as far as I am aware. I recently went without an internet connection for approx. 4 months, and regularly started steam in offline mode and played (valve and non-valve) games throughout that period with no lock-out occurring. While I can't guarantee that it doesn't cut-out at 6 months or a year without connection, I highly doubt it.

Opportunist: Think we can coin something like Godwin's law out of it?

How about

  * As an online discussion goes on, the probability of a discussion of U.S. foreign policy approaches one.

Or perhaps a 'Kevin Bacon' approach:

  * If the lowest 'Bush number' of any discussion topic (X) linked to another is N, X's Bush number is N + 1.
  * The subject of U.S. foreign policy has a Bush number of 0.
