You lot have no bottle :

Now when I were a lad I were told I weren't a shiner unless I could set me ladder on sloping ice, with only one style end on the wall, then run up it and stand on the very top rung with a bucket of boiling water (to stop it freezing on't'glass) in one 'and and me squeegee in t'other and me scrim in me teeth.
I could do it an' all, but 'ad ter stop in 1978 when some silly b****r tripped over me ladder and knocked me off.
Never been the same since
