I watched a bit last night before going to bed. It was funny that we were talking about ST alumni. Last night I watched Once Upon a Time with Buster Keaton and the man that played the tribble merchant in TTWT was in it. It reminded me that in an earlier season I saw another guy that had been on ST as well. While not really "alumni" it was still funny to see.
