MY Uncle wanted to get rid of me
My Uncle was making something when I bugged him by repeatedly asking what he was making. In frustration he told me he was making "a rudder for a ducks butt".
Being under 8 years of age I took him seriously.
One day I was playing with tools and my grandmother asked me what I was doing.
I replied, "I'm making a rudder for a ducks butt".
It freaked my grandmother out and she often told this story to other friends and family members.
