Episode Summary
It's an innocent day in Danville. The grass was green, and there wasn't a cloud in the sky. Buford, Baljeet, and Heidi come over, and Buford seems to have something on his mind. Baljeet has a bad feeling about this. He hopes he doesn't challenge Candace to anything again. That's not what he's here for. It has come to Buford's attention that people have taken interest in flying. A plumber can gain that ability with a feather, a sponge can do it by inflating his pants, and there can be an animation goof in a video about Jericho. Phineas asks how he knows all this. Buford says to get into pop culture. Then, he challenges Phineas to learn how to fly. He thinks it'll be easy. He just needs to soup up some rocket engines, bird feathers... but that isn't how Buford wants him to do it. He has to do it without any gizmo of any sort. Phineas twitches and thinks "not again."
