Haha, heard that story years ago..
I still pee on me hands in the shower if I'm getting hacks on my fingers.. [emoji6]
Thats what my boss used to say when on site, seemed to be much colder back then, more snow and ice ( i could be imagining it)
But we worked in the countryside all the time, farmhouses/barns ect,
When our hands were seizing up
" pee on em son, soon warm up "
