Michael J. Massimino as Mike Massimino
This is one of those instances where who this character is in real life is freaking cool. Michael Massimino is a professor of mechanical engineering at Columbia University and he’s also a former NASA astronaut!
Massimino has a reoccurring role as himself on The Big Bang Theory. We can’t imagine what it must be like to play yourself in a huge and popular television series!
Vernee Watson as Althea
63 year old Vernee Watson is a well known actress, author, voice artist, and acting coach. Not convinced? Watson is Vernajean Williams from Welcome Back, Kotter.
Or better yet she’s Viola “Vy” Smith on The Fresh Prince of Bel-Air. Anyways she had a reoccurring role on the show from 2006 to 2016.
