Mario and Lesley Gore.

Have you ever noticed that the part of the first level music of the original NES Super Mario Bros.--the part just before it repeats--is exactly the same as a portion of Lesley Gore's classic "It's My Party"--the part right before the chorus ("Judy and Johnny just walked through the door / Like a queen with her king / Oh what a birthday surprise / Judy's wearing his ring")? Well, maybe not exactly the same. But pretty close. Eerie, no?
