I've had my Defender Optimus Prime for about a year or so, and I've always had a problem with this knee/thigh area.
You see these two....er....tabs here?:

Well, when he's in robot mode, they only go this far into his thigh area:
(I appologize for the blurry photo)

If I even try to get him into some kind of action pose, his thigh/knee part comes undone and he falls over. He pretty much just stands on my shelf, looking rather bored.
Is there anyway to fix this?
