It's Gonna Get Dirty Again

"It's Gonna Get Dirty Again" is a Sesame Street song performed in episode 3033. In the song, Oscar  cheers up  Irvine  when she sees clean clothes by singing about how eventually, the clothes will become dirty again (with two back-up Grouches who appear from under some laundry). Sure enough, Maria and Gordon bump into each other with their clean laundry and spill them.
