I'm pretty sure that this related to "Mac". It was from something I watched many moons a go, but it stuck with me and I have no reason to doubt it's accuracy.
After the Embassy siege all the guys involved went back to their 'staging base' (not a clue what the real term is). They were all there watching themselves on the TV and having a beer, when in walks Maggie Thatcher (the PM) with some other cronies, who wanted to say a personal thank you to them. She walked into the center of the room and was about to address them, but in doing so blocked the view of the TV for a couple of the guys sat around, to which Mac loudly retorted, "Get out the ******* way!!".
She duly did so without a word.
RIP Mac
