Kristen Bell might have expected this from Nickelodeon, but PBS??
On a recent trip to Sesame Street, the Hit & Run star found out that all the world's a stain when she tried to teach kids the word splatter!
Oh well! That's what you get when you ask for help from Elmo and Abby!
For more great videos, with celebrity guests like Zac Efron, Timothy Olyphant, and Halle Berry, make sure to make your way to Sesame Street!
For now, ch-ch-check out the bonus video AFTER THE JUMP to see Kristen's hunky hubby Dax Shepard grab his guitar and get amplified!
