The Lion Sleeps Tonight (Dexter)

"The Lion Sleeps Tonight," also known as "Mbube" or "Wimoweh," is a song that gained significant popularity after its use in the animated television series Dexter's Laboratory, created by Genndy Tartakovsky. In the episode "Dee Dee's Room," Dexter's sister Dee Dee discovers a button in Dexter's secret laboratory that plays the song. She repeatedly presses the button, causing Dexter immense annoyance and leading to comedic chaos.

The song itself is a Zulu folk song written and originally performed by Solomon Linda and the Evening Birds in 1939. It was titled "Mbube," which means "lion" in Zulu. The song gained international recognition through various cover versions, most notably by The Weavers in 1951 ("Wimoweh") and The Tokens in 1961 ("The Lion Sleeps Tonight").

Its inclusion in Dexter's Laboratory introduced the song to a new generation and solidified its place in popular culture. The repetitive and catchy nature of the song, coupled with Dee Dee's incessant button-pressing, made it a memorable and often-referenced element of the series. The episode's popularity contributed to a renewed interest in the song's origins and its various versions throughout history.
