Office star John Krasinski is popping over to Sesame Street to teach us a valuable, hilarious lesson about vocabulary, with a little help from proud little lamb owner Murray. In an exclusive clip, Krasinski tries desperately to explain the definition of the word “soggy.” Shenanigans ensue, involving a sock, a sponge, and an elephant. Krasinski looks like he’s having a ball, so clearly there are no hard feelings about Elmo’s spot-on Jim Halpert impression. Watch the video below:

Krasinki’s visit to Sesame Street will air Dec. 29.
