Epic 23 has several, but just to name one: Hyde suffers a heat-inducing attack, leading to his going through all sorts of summer methods to beat the heat, including wolfing down shaved ice. Gilligan Cut to Hyde's Epic icecream headache.
The highlight of that episode has to be the epicRocky Roll Call between Alata, Hyde, and Agri, which starts out serious but soon devolves into an Overly-Long Gag. The part that pushes it into Crowning territory is that while they're caught up in this they're paying absolutely no attention to Eri or Moune, who they're supposed to be rescuing.
Episode 24. After the team has won thanks to the help of getting their Mid-Season Upgrade from the Miracle Gosei Headders, they all transform back to their regular forms, talk to the Miracle Gosei Headders, and Miracle Dragon Headder forgets its own strength for a moment when it headbutts Alata!
Then there's the gang's methods of helping Agri train for a 100-meter dash competition in Epic 36, culminating in Gosei Knight assuming Groundion form to chase Agri across a field.
