"Oh the night is dark and stormy
and stay by the fire I ought-a
but I've yet
to walk my collie
and she needs to pass her water!
will ye go, lassie, go.

For Three hours now I'm waiting
Icy cold and shiver-shaking
She's examined
every grass-blade
And she's yet to take a squat-a
will ye go lassie go!

(first time I heard this there was a dog in the audience...
every time "Will ye go lassie go" was sung the dog would give a single
bark. Had the entire place in tears!)"
