the hotdog, chocolate fudge and cookie

early in the morning in the car, half asleep and hungry, and then the song started to play from the radio station. the only lyrics that got picked up by me – hotdog, chocolate fudge, i want cookie.

how are the 3 food related to the king of rock and roll?

actually, the correct lyric should have been – hot dog, jumping frog, albuquerque.
