First lady Michelle Obama has shown us more than once that she knows how to be funny. She made us laugh when she did the "Evolution of Mom Dancing" with Jimmy Fallon. She laughed herself alongside Jay Leno when she got him to eat his veggies. Earlier this year, she played straight man to Will Ferrell funny man in a video to promote Let’s Move.

Her latest foray into comedy is a cameo in a Funny or Die fake movie trailer titled "Snackpocalypse." The video stars the "Carrie" remake star Chloe Grace Moretz and Tyler Posey from "Teen Wolf." The fake movie is about a high school where students turn into junk food zombies and Posey must save the day with fresh fruits and vegetables. The first lady’s appearance happens near the end.

It's no surprise that Michelle Obama, the champion of healthy eating and curbing childhood obesity, would agree to do a cameo in a comedy video about the dangers of junk food. As for it being for Funny or Die? She's not the first Obama to star in one of their videos. Her husband already took his turn with the comedy video website in an episode of Zach Galifianakis' "Between Two Ferns."
