Ohhh... it's CATCHY! Original Pinner said: "This morning I walked into a fifth grade classroom and they were singing the song "What I Am" by Will.i.Am. And Yes, it's a song he sang on Sesame Street. But these fifth graders were LOVING it. Their teacher told me this was their new theme song. Let me tell you....all the kids were standing up and singing this song LOUD and with hand movements. It was so awesome because I could see how much they BELIEVED the words to this song.".
