Well, well, well. This is taking "clinging on by my fingernails"...

Well, well, well. This is taking "clinging on by my fingernails" a bit to the extreme. It is rather exhausting and energy sapping in this rather precarious position.
I feel like I am clinging on to the last bit of the caboose as the track heads across a deep canyon on a rather rickety bridge with the freight wagons ahead swaying and clattering noisily up ahead.
O me miserum.......woe is me. What is to become of me.? Yatchy......HELP !!!!!
