"Good Night" (also known as "Good Night Simpsons") is the first of forty-eight Simpsons shorts and the second segment of the third episode of The Tracey Ullman Show on April 19, 1987. It originally aired on Fox in the United States and marks the first ever appearance of the Simpson family — Homer, Marge, Bart, Lisa, and Maggie — on television. After three seasons on Tracey Ullman's show, the shorts would be adapted into the animated show The Simpsons. "Good Night" has since been aired on the show in the episode "The Simpsons 138th Episode Spectacular" (in its entirety), along with several other Ullman shorts, and is one of the few shorts to ever be released on DVD, being included in the Season 1 DVD set.
