While waiting to be seated in a restuarant, I saw a man who looked familiar, but couldn't remember the name. I greeted him with "Bob? Aren't you the father of one of my children?". He recoiled and retorted "My name is NOT Bob and I am most certainly not the father of one of your children". The woman who was with him looked at him questioningly, he grabbed her arm and stormed off before I could explain that I facilated "Getting to Know You" classes at a local SPCA and had groups of "regular" children.
