I have no idea about building ribs, but I am in Scotland and am often refeRred to as a "tube" .
I think this is a term of extreme reverence and endearment and I think qualifies me for the job of sampling the wine, women and song while being paid!!!
As recently as yesterday I was instructed "Away ya big
tube!!"....which I think is a even bigger compliment, inferred travel and I am obviously ascending the ranks. If I become a "tube maker", does that make me boss?
Where do I apply!!! LOL
