I wonder if there are people who can suck their poop back up into their butts when its almost all the way out, like some people can do with their spit.
I think that if someone can, it should be called a "turtle-head-fake."
I know that turtles can do this, because my friend Chris once told me a story about his turtle, Oscar. Apparently Oscar was pooping a ginormous turd, and then Chris walked into the room and Oscar got nervous and sucked it back in.
Chris was concerned for oscar's health, but Oscar turned out ok.
