I suppose this is "old hat" to most people, but why did "Happy Days" character Wayne Weber end up being called Potsie?

Thank you

His real name was Warren Weber (Anson Williams), but he was called Potsie by his mother, due to his fondness for making things out of clay as a child.

I bet you thought it was a drug reference.  And you were the first to ask.
