Chris is doing his laundry at the Sesame Street Laundromat. When he is folding his clothes, he discovers that a sock is missing. All socks come in pairs so he needs to find the matching sock. Abby appears and has a new "two trick" that turns one thing into two things. Abby waves her wand and makes a pink polka dot sock appear but it doesn't match Chris' striped sock. Abby tries another trick called the "more trick" that her mommy uses when she needs "more" of something. Four different socks appear - an argyle sock with diamond shapes, a white gym sock that does jumping jacks, a baseball playing red sock and a baby sock. They don't match Chris' striped sock either, but they do sing and dance "the five-sock conga". Just then, another customer at the laundromat finds a sock which got into her laundry by mistake. It's Chris' matching sock! Chris rushes out of the Sesame Street Laundromat with the five socks congaing after him looking for a new home and a warm drawer to curl up in. THEME: Mathematics K / 5
