It's funny how google, and my mind, works.
I typed in Arnold Horshack, Arnold Horshack hand raised, Arnold Horshack ooh ooh ooh, I can't even remember what else, and I didn't a single picture of him with his hand raised.
And then Tiggie comes along and types in Horshack, and voila!
Jill, you done good with that baby girl!
