This might be my favorite episode for the whole season. It's only because I can associate with it so well. It features Quibble Pants returning and revealed that he's raising a daughter with his wife. There goes all the shipping with him and Rainbow Dash! Anyway, this episode features him trying to connect with his daughter by wanting Rainbow Dash teach him to become an athlete. Patton Oswalt (his voice actor) actually got his own wife and daughter to voice them in this episode!
Oswalt's own daughter doesn't share the same interests as him, as he's into "My Little Pony" and he did this voice work to honor her! Oswalt himself had a dad who wanted him to be an athlete, but he was more into movies and pop culture. It's so wonderful that he did something that reflected his real life so much. I know what it's like as my brother is a basketball fanatic and I'm much more into pop culture. I was a member of a teeball team as a kid, but never enjoyed it. I'm talking to you, Mom! ****
