Leela, Telly and Elmo are folding clothes in the Laundromat when Inspector 4, Judah Friedlander, comes along to inspect for things that are in groups of four. Inspector 4 can't find four of anything and threatens to shut down the Laundromat! Luckily, Elmo suggests counting the bottles of fabric softener. Time to count! 1,2,3,4! There are four bottles of fabric softener. They pass the number 4 inspection! Next, Inspector 4 visits Mr. Hooper's store. Inspector 4 inspects the peanut butter sandwiches. Oh no! There are ten sandwiches and ten is more than four. Telly gets an idea! What if he eats some of the peanut butter sandwiches? Telly eats one sandwich, then two, and then three more sandwiches so that only four sandwiches remain. Hooper's store passes the number 4 inspection! Last, Inspector 4 looks around the steps of Sesame Street and sees the letter "R" standing next to a rake. The Inspector 4 threatens to shut down the letter "R" because he only has one thing that begins with the letter "R," rake. Elmo has an idea! What if they find three other things that begin with the letter "R" and add them together? Elmo, Telly and the letter "R" find a Rose, a Rock, and a Rodent. They did it! They found four things that begin with the letter "R"! Inspector 4's mission is completed!
