|From the episode:||Stewie Griffin: The Untold Story/Stu & Stewie's Excellent Adventure|
"Short Shorts" is a song by the Royal Teens that was a #3 hit in the United States in 1958.
In "Stu & Stewie's Excellent Adventure", the third segment of Stewie Griffin: The Untold Story, a sixtysomething-year old Joe Swanson in the year 2035 sings it while flaunting the transplanted legs from his late wife Bonnie Swanson, which looked much too young to match a sixty-year old body, thus still attractive.
Joe: Who wears short shorts?
I WEAR SHORT SHORTS!!
