Jack Be Nimble is a nursery rhyme character, famed for his prowess at leaping over candlesticks. He appears in a Sesame Street News Flash sketch, where he is portrayed as a hippie who does not know what "over" means, instead going under and around the candlestick.

Jack finally jumps over the candle stick (and thereupon remarks that he broke every bone in his body). He contemplates suing Mother Goose after what happened, but is interested when a cow tells him that he should jump over the moon sometime if he thinks that simply jumping over a candlestick is so painful.
