Like the kid I went to elementary and middle school with. His name was really ray, and his last name kind of rhymed a little bit with pasture. One day some kids were horsing around in the playground and one of Ray's shoes got tossed over the fence into a cow pasture. He climbed across to get it and a cow/bull (forget which) saw him and started for him and he nearly pulled the fence down getting back over it. Ever after he was known as Cow Pasture Last Name that Kinda Rhymes with Pasture.
Or some friends of mine. Their son is named Joshua, but when he was first learning to get around, instead of crawling he would get up on his feet and hands, just like a Monkey. He was called Monkey for years.
