Say what you will about old-fashioned wooden toys — they do keep a dad involved.
Back when I was a kid, I wanted a train set for Christmas so, so badly, and I ended up pointing out what I wanted: a full set for $10, which was a steal even back in the late 70s. Now, keep in mind that the average lifespan of a Christmas-morning toy train is said to be four hours. My dad kept that thing running for years.
Now, when I return a fixed toy to the kids, they happily treat me like a hero... and I start to wonder if, just maybe, Dad had as much fun fixing that train as I did breaking it.
