SPOILER: After the end credits there is a brief scene slowly panning over desert bushes. Ed pops up from hiding with a bush on the top of his head as camouflage, quickly looks left and right, then drops back down into hiding again. As Gabe had predicted, Ed is still alive.
SPOILER: A minute-and-a-half into the end credits, we see Hap and Sweetie-Pie do their "Swanee" talent show musical number in its entirety (one minute) as the credits scroll.
