You have to discover when you're inadequate to be funny and you don't know you're inadequate when you're a kid.
I still think of that guy I was without a wife or kids, and I still want to entertain that guy. The lonely guy, the frustrated guy, the guy with no money - this is the guy who needs to laugh.
The best situation is being a single parent. The best part about is that you get time off, too, because the kids are with their mom, so it's the best of both worlds. There's a lot to be said for it.
