Revisiting Ben Harper

So, in the first installment of "Delicious as an Enchirito?", it was decided that Ben Harper is, surprise surprise, delicious as an enchirito.

And since I saw him last night, I thought I'd just reiterate the information. He's awesome and wonderful--and wasn't wearing his wedding ring last night. But that's probably just for the show. I think he and Laura Dern and their cute kids are probably doing just fine. I've given up hope. Laura is a nice lady--though she could use a few enchiritos--and I am glad she snagged Ben after horrible Billy Bob skipped out on her for...

Some trivia:

1. for whom did Billy Bob leave Laura?
2. And in what dramatic fashion did he do it?
3. who introduced Laura and Ben?
4. what does Laura have that i don't?
