Yeah, I don't think I'd be up to portraying the Brig doing anything that might make people queasy - I mean, he's the Brig - it's like the Queen or something... ;D

And yeah, I'm a firm believer that if it's funny it excuses anything at all, but of course there's always the risk some people won't think it's funny...

And as for whether the plot (or lack of it) makes sense, well - there'll be plenty of time for explanations later (and more than explanations if it happens to be Ace Rimmer)!
