Penny is so pretty! :-) I'm drawing a blank on what "CRT" might stand for in this context.

Given that Steins;Gate is in the tags, they're cosplaying as the father-daughter duo in that series. If that is the case, the CRT is probably the type of tv that the father in Steins;Gate is so obsessed about FYI the "I heart CRT" in the apron.

The VA of Ironwood is the same guy who does Mr. Braun hence the seiyuu connection.

I think he just likes old T.V.s

Cathode Ray Tube ffs. Get off my lawn fam.
