Okay here goes: Richard O'brien and Barry Bostwick, the guys who do the voices of Dad and Grandpa respectively, both worked as major roles on The Rocky Horror Picture Show years ago. Strangely, Dad and Grandpa never actually interacted with each other on screen. That is, not until now. So the writers are clearly aware that we noticed the lack-of-interaction so they made that scene really awkward and uncomfortable.
