I use the bowline for everything. I remember in the scouts my Scout Master showed us how to tie the bowline with one hand with some rope wrapped around your waist.
He tied a rope to the rafters, stood on the edge of a table and wrapped the rope around his waist and fell backwards. Before we knew it, he tied the knot so fast and was just hanging there.
