Anyone know the reasoning for Don "H2O" Haley's nick name?

I have a number of items from Don "H2O" Haley's hobo nickel collection.

I've always been curious about his middle name. Anyone know "H2O" became his middle name?

Here's a train set of his I picked up made by Ron Landis and Joe Rust.

He collects small trains?

I know about HO Scale trains https://www.modeltrainstuff.com/ho-scale/ .

Is there a "H20" Scale train?

When I search Google for "H20 Train" I get machine learning training data set articles!
