This is Bradley Gregg who is a friend of Keith's, an actor who was on Silver Spoons (!), and, oh yeah, just happens to be married to Dawn Schroder (the sister of Ricky Schroder!!!).
I'd really like to be able to tell you that when we ran into the two of them at Costco, I was able to remain cool, calm, and collected upon learning of Dawn's identity, but we all know better than that. I'm fairly certain my squeal could've been heard from space.
