The file
A kid on a dock spells the company name one letter at a time, and fifty years later a whole generation can still do it on command. Richard Trentlage wrote the original wiener jingle in 1963 for a contest; the bologna sequel a decade later became the bigger earworm.
It is the reason the Oscar Mayer Mandela effect exists: the letters are sung, and people still spell it wrong. The Wienermobile still visits schools and the kids still know the song.
