TSR's Funniest Gamming moments

[Zee]

In Portal, in the level with the turrets intended for cyborgs or whatever, I felt bad for the turrets, so I carefully picked up each and every one of them, and put them behind the glass in the start of the level. I had nine of the turrets side-by-side, jam packed as well as could be done. I found out if you don't look at the turrets, and even if they see you off-screen, they won't tip each other over.

I finished the level, looked at the turrets and watch them all kill each other as they expanded and tipped like dominos. Although one of them just shot straight upwards and sent all the others flailing.

It was awesome.
