That's a bit too small for my eyes, or at least for my screen resolution.
I remember the old Burns & Allen show (in reruns, I'm not that old). On occasion, George Burns, when he was trying to figure out what latest shenanigans Gracie Allen had gotten up to, would sit down in his living room and turn on the Burns & Allen show on his own TV. (What fourth wall?) So I'm wondering if Sandy's maybe trying to find out what the rest of the gang is up to by cheating and looking ahead. (OK, we know Doc's sleeping, or knocked out or whatever.)
Also... at a quick first glance, it looked a bit like Sandy had turned into a centaur. I had to blink a couple times to see what was really there, hence the subject line.
