GBB..normally I wouldn't admit to not knowing what you're talking about. I would normally give you a jolly rorkous pat on the back and shout "good one mate"...turn back to the bar, swill my pint, and think to myself "what the f*2k was he talking about..I'm too embarrassed to admit I have no idea"
But I'm really curious..please enlighten my obviuosly fatigued intellect
(hope it's nothing to do with those ladies of the night that frequent that dodgy bar in the corner of the LOS hotel)
