MaskedSingerA show that would seem to fit these bizarre times is “The Masked Singer” (Fox, 9 p.m.), in which singers (and sports stars) — all promised to be very very famous — are disguised in super-elaborate costumes and a panel of lesser celebrities have to guess who they are.

That the celebrities talk in voices that are also disguised by robotic altering techniques makes it even more bizarre. But saddest are the dim comments and guesses by the panel of Robin Thicke, Ken Jeong, Jenny McCarthy,  Nicole Scherzinger (the latter two of which have their own Botox masks on). Nick Cannon tries to make epic what is is as silly as the lineups tonight might indicate: Peacock vs. Hippo, Monster vs. Unicorn and Deer vs. Lion.
